DESIGN SERVICE OPENS MORE DOORS TO USING FIBRE IN CONCRETE

BLURB FOR ONLINE PUBLICATIONS

With the growing popularity and versatility of fibres in concrete, CHRYSO works with local fibre specialist Oxyfibre to offer customers a professional technical design service. This relates to custom applications of CHRYSO® Macro polypropylene fibres, which are considered as structural elements in construction. Oxyfibre’s Izak Louw says this design offering ensures that contractors get the most from this innovative technology.

 

MEDIA RELEASE – 08/11/2022

DESIGN SERVICE OPENS MORE DOORS TO USING FIBRE IN CONCRETE

The use of fibres in concrete goes back to Roman times, but modern fibre technology now offers contractors and end-users almost limitless possibilities, which can be brought to life by the specialised design service from CHRYSO Southern Africa and Oxyfibre.

 

Izak Louw, operations manager at Oxyfibre, explains that CHRYSO® Macro polypropylene fibres compete with the conventional steel mesh as a reinforcement for concrete. As such, these macrofibres are considered as structural elements, and must pass stringent tests to prove the strength and integrity of their physical properties.

 

“This creates the basis for us to offer a specialised engineering design service for the application of our macrofibres, not only for ground supported slabs but also for precast concrete,” says Louw. “We use the customer’s data on loadings, ground conditions and the kind of activities that will be carried out on the concrete surface – such as rolling loads and racking loads.”

 

CHRYSO Southern Africa has been the official distributor for Oxyfibre since 2016, with the two firms having built a strong working relationship for many years before that. Oxyfibre makes available both microfibres and macrofibres supplied by Adfil Construction Fibres, who Oxyfibre represents in sub-Saharan Africa. ADFIL Construction Fibres bases its manufacturing facilities – as well as its research and development laboratory – in Belgium.

 

“Most of our customised fibre designs relate to civil engineering applications, such as roads and industrial slabs,” he says. “However, we also provide the design service in smaller contracts for driveways, residential homes and requirements on farms.”

 

Working closely with CHRYSO, the Oxyfibre engineering team considers the customer’s needs and provides feedback on aspects like fibre dosage, the size of saw-cuts on a slab and the optimal thickness of the concrete. A good example of the fibre design offering was for a building project where the contractor was looking for an innovative solution.

 

“The building had a large number of service conduits to be installed between the hollow core planks and the structural topping,” he says. “It was clear that there would not be enough space to use conventional steel mesh reinforcement.”

 

The contractor asked CHRYSO and Oxyfibre to find a solution that would allow space to install the service conduits and prevent cracking of the topping’s surface. The use of macrofibres did the trick, also saving on the time and cost of placing steel mesh reinforcement. Moreover, the fibres could be added to the concrete mix at the readymix plant, so there was no need for the storage or mixing in of fibres on site.

 

“With our tailored design service, we work closely with the customer to supply the required calculations and technical specifications,” he says. “We also produce a detailed commercial proposal that sets out the benefits of CHRYSO® Macro fibres; our service comes with professional indemnity.”

  EditorLeave A CommentOn COSCO SHIPPING Brings Construction Vehicle Carrier Service To Southeast Africa

With the delivery of a carrier loaded with tractors, tankers and mining trucks to southeast Africa, COSCO SHIPPING Specialised Carriers has marked its first entry into the continent

 

M.V. FENG HUANG SONG, a carrier operated by COSCO SHIPPING Specialized Carriers, arrived in Africa after departing from the Port of Qingdao in Shangdon Province. It was loaded with 467 tractors, tankers and mining trucks and is the first dedicated service customised and launched by the company for FAW to deliver its construction vehicles to the continent.

Based on a full analysis of the customer needs, the project team decided to use a multi-purpose carrier with three decks and designed the service specifically for the customer considering its needs.

In recent years, as many Chinese enterprises have implemented infrastructure projects and built factories in Africa, the local demand for construction vehicles is growing. Meanwhile, export difficulties encountered by Chinese construction vehicle manufacturers have also become more prominent due to the constraints of ro-ro ship transport capacity and the impact of the Covid-19 pandemic.

Since late 2021, COSCO SHIPPING Specialized Carriers has launched an innovative special express service for direct customers, providing customised logistics service solutions for customers, including the best loading ports, the most suitable type of ships, the fastest shipping route, the highest frequency of shipment to meet the customer needs and the quality assurance of professional service. It has laid a solid foundation to build an unimpeded international logistics supply chain for Chinese construction vehicle manufacturers.

ARE YOU PREPARED FOR DIGITAL DANGERS?

ARE YOU PREPARED FOR DIGITAL DANGERS?

With today’s revolution in automotive connectivity and the exponential growth in the number of connected vehicles on the road, it is imperative for the automotive industry to understand, predict, and combat rising cybersecurity threats.

Leading international market research company ResearchAndMarkets.com states that the global automotive cybersecurity market is expected to grow from US$2.04 billion in 2022 to US$4.16 billion in 2026, at a compound annual growth rate of 19.5%.

Global Market Insights, another global market research and management consulting company, notes that the passenger vehicle segment held over 81.9% of the automotive cybersecurity market share in 2021. It also highlights that commercial vehicles are more prone to cyberattacks, however, due to the emerging trends of vehicle connectivity and surging hybridisation, electrification, and automation in automobile technology.

“Historically, trucks have been largely self-contained electronic systems, so protection against external attack was not a significant risk,” explains Josh Foster, Garrett Motion’s* connected vehicles division general manager. “However, increasing digitalisation and the associated interfaces like Bluetooth, wireless, cameras, sensors, and other advanced driver assistance systems that are an important part of today’s truck world are making these highly complex systems more vulnerable to outside cyberattacks.”

Florian Rehm, a cybersecurity expert at the commercial vehicle control systems (CVCS) department of ZF Group**, agrees – adding that today’s passenger vehicles have as many as 100 electronic control units (ECUs), compared to only five ECUs two decades ago. “And instead of each ECU controlling one task, the functions are distributed across multiple ones,” he points out. “Additionally, a high-end car contains as many as 100 million lines of code – five times more than in fighter planes. We see these trends reflected in commercial vehicles as well, and all of this IT complexity creates potential new attack vectors for cybercriminals.”

A FLAW FROM WITHIN

In its blog Addressing the Cybersecurity Risks, ZF highlights another weak point in these systems: “Take the Controller Area Network (CAN) as an example. The CAN communication protocol is a standard describing how information is exchanged between different components and sensors inside a vehicle. Like other automotive technologies (including ECUs), the CAN was not designed to be connected to the internet.

“Developed in the early 1980s, this onboard network operates on the premise of ‘trust’. In a connected environment, this principle leaves the door open for malicious attackers to gain control over the vehicles and manipulate them remotely. By speaking in the name of an ECU, an attacker can easily trigger arbitrary vehicle functions.”

The ZF piece adds that a common protocol for the CAN in commercial vehicles is SAE J1939. “This standard, which plays a key role in network ECUs, has been around for many years, and continues to grow in popularity due to its usage in telematics while ensuring interoperability of different systems,” it notes.

“As an open standard, SAE J1939 has vulnerabilities. Academic researchers have shown how easy it would be to launch attacks on a CAN bus using this protocol, if they could get access to the vehicle network. Once they gained that access, the researchers could control critical systems, including the ability to accelerate a vehicle in motion and disable the brakes.”

NOT JUST REMOTE CONTROL

Vehicles aren’t the only business components at risk, however, as supply chains can be exploited as well. ZF writes: “According to the Transported Asset Protection Association***, the estimated average daily loss from supply chains was €378 058 in the Europe, Middle East and Africa region in 2019, and the combined loss of major crimes (€100 000 or more) over 12 months was more than €96 million. In the US, the cost of cargo crime is estimated at US$10 to 25 billion per year. Only a fraction of the thefts are actually reported, so the losses are much higher in reality.”

Theft from road vehicles accounts for the majority of cargo thefts. In the past, the biggest problem was related to physical security, but supply chain security is evolving beyond the traditional environment to the digital realm: “Taking advantage of technology, cargo thieves could hack into an online tracking portal to access manifests, pick up information and other sensitive data; re-route cargo to a different destination by spoofing information; or pick up cargo using forged documents,” notes ZF.

The global technology supplier adds that, up to now, automotive technologies have not taken a security-by-design approach. The industry is now recognising the importance of cybersecurity, although adoption of security measures has been slow.

“A study commissioned by SAE International and Synopsis**** found that 84% of the nearly 16 000 IT professionals surveyed in the automotive industry were concerned that cybersecurity practices were not keeping up with the evolving technologies. Yet, 30% of the respondents said their organisation didn’t have a cybersecurity programme or team, and 63% tested less than half of their technologies for vulnerabilities.”

ZF’s CVCS strategy is best summarised by Christian Brenneke, senior vice president of product engineering at ZF’s CVCS division: “Today’s digital technology is the foundation of our knowledge-based society and enables mind boggling opportunities, but as systems become more connected and integrated, we see the number of vulnerabilities growing. This is why the implementation of dedicated cybersecurity standards has to be a top priority in the commercial vehicle industry as well as ensuring a security-by-design approach for every step of our development projects’ life cycles – starting from their specifications all the way to their validation.”

Rehm adds: “We have tested the early versions of our products to understand their resistance to cyberattacks, and we also monitor hacker forums to stay on top of how our products are misused. We have also started to evaluate all of our suppliers regarding cybersecurity, and have integrated that into the development process.”

According to the ZF blog, over-the-air software updates, Internet of Things (IoT) and automated vehicles are among the other trends that will drive advances in the next generations of commercial vehicles. “The industry will continue to transform and innovate, but progress is not possible without an emphasis on cybersecurity. As the industry looks to the future, it’s critical to understand the risks of these new technologies – and put mechanisms in place to address them,” it concludes. You have been warned!

Barrick’s Lumwana copper mine in Zambia gearing up for the future

Barrick’s Lumwana copper mine in Zambia gearing up for the future

Barrick’s drive to transform the Lumwana copper mine in Zambia into a Tier One asset with a life extending beyond 2060 is picking up speed with a strong performance in the past quarter adding impetus to its continuing production ramp-up.

Briefing media at a site visit here on July 7, Barrick President and Chief Executive Mark Bristow said the mine’s full potential was only now being revealed. Additional expansion opportunities, identified through an updated geological model, are currently being assessed, while drilling at the Kababisa prospect highlights potential mining flexibility through higher grades. The Lumwana pre-feasibility study is progressing in line with its plans to transform its long-term copper profile through the delivery of the envisioned super pit.

“Since Barrick refocused its strategy in Africa in 2019, Lumwana has become a key element in the expansion of our strategic copper portfolio and a significant contributor to our bottom line. At the same time its importance to Zambia has grown. Since 2019 it has contributed more than $2.3 billion to the country’s economy in the form of royalties, taxes, salaries and purchases from local suppliers,” he said.

Barrick has a global policy of sourcing its suppliers locally and last year it spent $432 million, 83% of its total procurement, with Zambian suppliers and contractors. It has also launched a ‘Business Accelerator Program’ to build the capacity of Zambian contractors in the mining supply chain.

A slide summarising production improvement at Barrick Lumwana

Similarly, Barrick is committed to local employment. Currently 99.3% of Lumwana’s employees and 98% of its contractors are Zambian nationals, both industry-leading statistics. Lumwana is a participant in the United Nations’ REDD+ project, which is designed to reduce greenhouse gas emissions from deforestation, and the mine has engaged with its communities on this initiative.

Looking at the mine itself, in the presentation accompanying the announcement, Barrick said that Lumwana is on track to achieve 2023 production guidance as the operation ramps up after the wet season, reopens the Malundwe pit, and smoothly transitions to owner miner operations. There is also a plan to to transition away from contract mining in 2023 – with an investment of US$115 million being allocated to implementation of an owner miner waste stripping fleet.

Barrick recently stated: “During the fourth quarter of 2022, we began a transition to an owner miner fleet at Lumwana following a study which concluded that this option could result in a 20% cost reduction within the first five years versus contracted services. Separately, an owner miner strategy positions the operation well for future potential expansions including the Super Pit, which has the potential to extend Lumwana’s life into the 2060s.”

From the processing side, there has been a continuous improvement of processing stability leading to higher throughput and the mine is working to exceed the new base set as it moves into the second half of 2023. Recovery has also stabilised following the higher blend of fresh ore from the pit as mining ramps up. Significant investment has been made over the last few years in the new fleet leading to continuous improvement in availabilities, with the latest batch coming into production in April 2023. A new stripping fleet started arriving in Q2, which will continue throughout the year and is expected to see the stripping increase with the fleet arrivals.

Mining originally began at the Malundwe pit in 2008 by Equinox Minerals (Barrick acquired Equinox in 2011), and the operation ran successfully for some years as a trolley assist mine, with trucks going up ramp to feed a primary gyratory, then the ore utilising a 4.5 km conveyor to the plant. The lower grade Chimiwungo or ‘Chimi’ pit (in fact now three separate South, Main and East pits) some 7 km away was then developed starting with South in 2012 and a new primary gyratory crusher and its own 3.5 km conveyor built to allow the Chimi pit to feed the existing plant. Malundwe and Chimi both operated for some years – Malundwe was higher grade but the initial pit closed due to being mined out leaving only the Chimi operation. Malundwe is now set to be reopened and expanded.

Planned Lubwe starter pits to the north could potentially provide a high-grade, low strip ratio plant feed further enabling the unlocking of the value within the envisaged Chimiwungo Super Pit and the potential 40-60 year mine life. Two other prospects – Kamaranda and Kababisa have potential as additional satellites. The Super Pit PFS began in Q4 2022.

The mine initially operated with a fleet of 31 Hitachi 254 t class EH4500 trucks and five 27 m3 EX5500 shovels – four of them face shovels and one backhoe.  Trolley assist was discontinued after mining moved from Malundwe pit. Barrick told IM that the main ramp to Malundwe is equipped with the trolley lines which are still in place however the pantographs were removed from the EH4500 trucks as they are now operating under full diesel power.

The current EH4500 trucks are reaching end of life and a competitive fleet replacement tender was held in 2021 where the Komatsu 290 t class 930E-5 was selected as the main new fleet truck type, with the EH4500s gradually being phased out. There are 15 of there running currently – the final new fleet will be a combination of 930E-5 and Hitachi EH5000 trucks – 30 in total. Four of the EX5500 shovels have been retired and one remains. The mine now operates three Komatsu PC8000 and three PC7000 shovels.

With emissions targets set by Barrick just as other top tier miners, IM asked if there was any plan to look again at running a trolley line: “In line with our commitment to reduce green house gas emissions we are in close discussions with our technology partners and OEMs on how to substitute fossil fuel with renewables. The feasibility of trolley assist is under investigation and consideration to ramp design is part of the expansion PFS that is underway.”

Aside from adding new equipment, Barrick added that its people are its greatest assets and training and upskilling is of cardinal importance. “This process starts with modern simulators we acquired to ensure that we can pick those with the best potential and continuously hone their skills to ensure they get the best out of our new assets. We have also reviewed our maintenance practices in close collaboration with our OEMs and sister operations in NGM to learn from past experiences.”

Sandvik’s BEV momentum accelerates as it commits to Electric Mine 2024 Platinum Sponsorship

The Electric Mine 2024 has come out of the blocks with a world-leading OEM and top battery-electric mining technology innovator in one of the top sponsorship slots. We are delighted to announce that we will be working closely with Sandvik Mining and Rock Solutions over the next year as one of only two Platinum Sponsors of the event. Amongst other things this will include a Sandvik BEV customer panel in the conference line-up, a Sandvik electric machine at the event plus Sandvik having one of the larger ‘Gigawatt’ booths in the exhibition.

It is entirely appropriate that Sandvik should be one of the companies headlining The Electric Mine 2024 two years on from the landmark 2022 event in Stockholm, where Sandvik was also one of the two major sponsors. But things have really accelerated since then – some mining companies, including juniors, mid-tiers and majors – have already taken the next step and committed to all-electric primary Sandvik fleets for their operations, both established and in-development – including Newcrest Brucejack, Torex Gold Media Luna, Foran Mining McIlvenna Bay and Rana Gruber in Storforshei to name a few. Others are starting new pilots and trials with Sandvik BEVs or are part way through them.

Not only that but there have been major technology steps forward as well – including a higher-capacity battery for Sandvik’s BEV loaders and trucks that delivers 36% more energy in the same envelope. And the company is establishing a new production unit in Malaysia for manufacturing underground loaders and trucks in an effort to answer growing demand for its BEVs. Plus the long awaited autonomous plus electric question has already been answered with the LH518iB – the AutoMine-ready version of the 18-t-payload LH518B.

Moving to drilling, with the DD422iE jumbo, DS412iE bolter and DL422iE production drill, Sandvik has a full range of electric options underground already. While the AutoMine® Concept Underground Drill, a cabinless BEV drill, shows what is coming in the future. On the surface, its full electric concept rig is an ideal platform to build on as the OEM works towards its stated goal of having a complete range of electrified surface drilling solutions in all hole sizes by 2030.

Finally – what also makes Perth an ideal hub for the event in 2024 is that Sandvik is playing a central role in the electrification of Australian underground mining. The world’s leading underground contract mining market is a great place to hold an event like this. Contract mining giant Barminco this year is deploying Sandvik’s largest BEV, the TH665B, at AngloGold Ashanti’s Sunrise Dam operation in WA. The other global contract mining major Byrnecut has agreed to purchase six of the all new LH518iB machines with AutoMine® for use in Australia. The OEM is supporting all of these operations and more with a recently opened purpose-built workshop and warehouse in Perth.

Sandvik’s first South Africa-manufactured screen destined for gold mine in northeast Africa

Sandvik Rock Processing says it has marked a significant step in its expansion across Africa with the successful completion of its first South African-manufactured screen package.

This milestone project was undertaken at the company’s Spartan facility in Johannesburg, which already produces the Kwatani and Schenck products as part of Sandvik’s screening solutions offering. The capability to also produce the Sandvik original screen range signals a new phase in Sandvik’s African presence and growth, the OEM says.

Riaan Steinmann, Europe, Middle East and Africa Operation Director Screening Solutions at Sandvik Rock Processing, says the achievement is a testament to the facility’s local design and engineering prowess. He emphasises the South African facility’s capability to build high-quality vibrating screens from raw materials, which also includes a range of exciter gearboxes using locally procured castings.

This innovative approach enables the company to maintain strict quality control and facilitates shorter delivery times for its customers, thereby improving the customer experience significantly, Sandvik said.

The screen package that marks this milestone was specifically ordered by a gold mining client located in northeast Africa. It includes a vibrating grizzly screen with a motor-driven exciter, five feeders and two custom-engineered feed-in chutes.

Steinmann praised the facility’s streamlined processes and the benefits of local procurement, which collectively allowed the project to be successfully completed within an impressive timeframe of three months.

“Manufacturing screens in South Africa represents the same standard as those produced in Europe or India,” Steinmann says, underscoring the global quality benchmark. He also notes the multiple benefits including reduced shipping times and costs due to Southern African Development Community trade agreements. Moreover, he highlights the positive impact on the local economy through exports and increased capacity, leading to job creation.

“Importantly, we aim to serve not only the African continent but also other regions within the Sandvik Rock Processing group,” Steinmann concludes. “The successful execution of this first Sandvik screen package has not only underscored our position as a world-class manufacturer but also underlines our ambition to become Africa’s preferred screening solution partner.”

NHL hails first all-domestic Chinese ultraclass mining truck

On July 12, the leading Chinese mining truck OEM Inner Mongolia North Hauler Joint Stock Co (NHL) and Chinese coal giant CHN Energy through its division Zhunneng Group held a delivery ceremony for a 300 ton class diesel-electric drive dump truck at the Haerwusu opencast coal mine.

The truck is unique is that it is the first large mining truck in China to be constructed mainly of Chinese-made components – including the engine, electric wheel motors and other major parts.

Zhang Jufu, Director of the Investment Planning Department of the Autonomous Region’s Office of Industry and Information Technology, Bai Guosheng, Deputy Director of the Baotou City Bureau of Industry and Information, Guo Haiquan, Deputy General Manager of NHL, Cao Yong, Deputy General Manager of Zhunneng Group, and other relevant personnel attended the delivery ceremony.

​NHL said that the delivery of the 300 ton ‘domestic mining dump truck’ is testament to the depth of cooperation between NHL and Zhunneng Group who are jointly promoting the benefits of localised construction, “breaking the dual monopoly of imported product technology and price,” and its advent also marks the breakthrough of high-powered diesel engines for mining heavy trucks in China.

It added that many the development of domestic core technologies such as electric drive systems has enhanced the comprehensive strength of China’s key basic components, basic materials, basic processes, industrial technologies and other aspects of mining trucks, which collectively is highly significant and an important milestone in the development history of electric wheel mining trucks in China.

This model is the first domestic large mining truck with independent intellectual property rights, which is equipped with a high speed diesel engine developed by domestic manufacturers and equipped with an engine intelligent supervisory control system. For the next step, NHL says it will continue to cooperate with Zhunneng Group to successfully trial the truck, continuously improve its performance, and build it into a mining truck with high reliability, high durability and higher quality.

At the ceremony, Zhang Yaobin, President of the Product Research Institute of NHL, delivered the truck’s symbolic “golden key” to Wang Jiming, Deputy Mining Director of Halwusu opencast coal mine. Zhang Jufu, Bai Guosheng, Cao Yong, Guo Haiquan and Wang Jiming together cut the ribbon for the truck.

Leo Lithium awards Corica Mali Goulamina open-pit mining contract

Corica Mali, a subsidiary of Corica Mining Services, has been awarded the open-pit mining services contract at Leo Lithium’s Goulamina project in Mali, a contract valued at approximately $348 million.

The contract, awarded following the completion of a competitive tender process and extensive due diligence, encompasses six months of pre-production activities at Goulamina followed by a fixed five-year term.

The scope of the contract comprises grade control, drill and blast, load and haul, and plant ore feed services. The planned material movement target is 18-20 Mt/y over the term. Corica has already mobilised to site under an early works contract and is currently undertaking the pre-strip and direct shipped ore (DSO) mining and crushing services.

Corica has a successful track record operating in the West African region for over 20 years, and has over 2,000 employees, according to Leo Lithium. It is currently providing large-scale mining services to a number of leading ASX and TSX listed mining companies across seven mining operations in Mali and neighbouring countries of Côte d’Ivoire and Burkina Faso. This includes the Syama open-pit operation (operated by Resolute Mining), the Waghnion mine (majority owned by Endeavour Mining) and the Tongon mine (majority owned by Barrick Gold).

Goulamina is a spodumene project with development underway, located 50 km west of Bougouni in Mali with all approvals and key permits received to bring the project into production. An updated definitive feasibility study was completed in December 2021, which outlined conventional open-pit mining methods involving drilling, blasting, loading and hauling. High-quality concentrate has been validated by test work, including production of concentrate grade of 6% Li2O and low mica. Leo Lithium and Jiangxi Ganfeng Lithium Co. Ltd own the project through a 50:50 joint venture, with the Government of Mali having the option to take up a 10% free carried interest in the project.

Leo Lithium Managing Director, Simon Hay, said: “We are delighted to appoint Corica as our mining services contractor following an intensive tender process. Corica has a long history and strong presence in Mali and will bring substantial local employment and supplier opportunities to the region.

“With the mining contractor now in place, Leo Lithium has taken another major step towards realising its target of first spodumene concentrate production in the first half of 2024. We look forward to working with Corica over the long term, commencing with DSO activities this quarter.”
