The government of Nigeria is inviting investors to explore the potential in the country’s mining sector at the 8th Nigeria Mining Week.

The country’s Minister for Solid Minerals Development, Dr. Oladele Alake said the event which is slated to take place this month will offer vast opportunities in the mining sector and is seen as a way to promote growth, profitability, and the shared benefits of the Earth’s resources.

Nigeria Mining Week

The 2023 edition of the Nigeria Mining Week will take place from 16^th to 18^th October with a theme ‘Capitalising on Nigeria’s critical minerals resources for its economic growth’. The key objectives of the event include knowledge sharing, investment promotion, sustainable practices, skills development, and infrastructure development.

Dr. Alake encouraged both local and international investors to take advantage of the opportunities in the mining sector. Nigeria is said to have vast mineral resources beneath its soil that hold the potential for growth and prosperity, not just for the nation but for the wider African continent.

The Minister emphasized the importance of collective action and collaboration between public and private sectors, civil society, and international partners to unlock Nigeria’s mining potential and contribute to the nation’s economic diversification. The country has further made substantial progress in the mining sector, implementing critical reforms, modernizing the regulatory framework, and attracting both local and foreign investments. These efforts have led to significant improvements in the mining activities in Nigeria.

Egyptian gold mine, Sukari, has released its revised life of mine plan, which targets several significant improvements.

The new plan outlines long-term increased gold production, with an average gold production of 506,000 ounces per year from 2024 to 2032, and an average of 475,000 ounces per year over the life of the mine (2024 to 2034). This represents a 5% increase in life of mine gold production compared to the previous year (FY22).

Life of mine plan

The plan includes various strategies to lower operational costs, such as an improved opencast schedule with a 40% reduction in the strip ratio, an increased underground schedule, and the integration of a gold gravity circuit to increase gold recoveries. The average life of mine all-in sustaining costs (AISC) are projected to be US$922 per ounce, which reflects a 34% reduction compared to FY22.

The plan indicates significantly reduced operational risk, which contributes to greater stability and sustainability in gold production. Sukari aims to reduce carbon emissions by connecting to the Egyptian national grid, which is expected to result in approximately US$41 million of annual cost savings based on current diesel prices. The plan also aims for a 39% reduction in greenhouse gas intensity compared to the previous year, reflecting a more environmentally friendly approach.

The plan identifies opportunities to extend the current 11-year life of the mine (2024 to 2034) through exploration and resource development in underground, surface satellite deposits, and adjacent exploration licenses. The plan also mentions that there are additional opportunities that have not been included in the life of mine plan, which could further reduce costs, carbon emissions, and improve operational efficiencies.

To stay ahead in the industry’s war for talent, AfriSam has over the years placed skills at the forefront of its people development initiatives. With its several training programmes, the company has successfully created a pool of talent, not only to the benefit of its operations, but the industry at large.

Glenn Johnson, General Manager Construction Materials at AfriSam, believes it is fundamental for the construction materials industry to develop people. The industry, he says, needs strong technical skills at the core of its operational excellence.

With that in mind, AfriSam has over the years invested significantly in its in-house training initiatives, namely the Engineer-In-Training, Artisan Learnerships, Trainee Works Manager programmes and general operational training. This has recently been expanded with the introduction of the Trainee Operational Managers programme for the readymix business unit.

Engineer-In-Training

Johnson explains that the Engineer-In-Training is a structured training programme for young graduates who have come through AfriSam’s bursary pipeline. “Selected individuals – those who demonstrate the best aptitude for the aggregates and readymix businesses – are integrated into the programme with the aim of developing a pipeline of electrical, civil, mechanical and mining engineers,” he says.

AfriSam has a two-pronged approach to developing its Engineer-In-Training graduates further. They are either given a chance to move into line management or to stay in their chosen technical discipline, be it mechanical or electrical engineering, or a multifunction of the two disciplines.

The Trainee Works Manager programme exposes candidates to all the critical aspects of works management on aggregate operations, including legal training, blasting certificates, financial management and, more importantly, people management amongst others.

The Trainee Operations Manager programme follows the same pattern, but with a specific focus on readymix concrete production, including technical specifications, product application and customer interface. Candidates are also exposed to the financial and operational aspects of the readymix business.

The Artisan Learnership Programme targets candidates who have completed their National Qualification Framework (NQF) courses, be it internal employees (18.1 learners) or external candidates (18.2 learners). “AfriSam has recorded massive success with these programmes,” Johnson says. “To provide context, since 2012, a total of 83 artisans – both 18.1 and 18.2 learners – came through the system.”

Despite the recent challenges brought about by the Covid-19 pandemic and the continued downturn in the construction sector, Johnson says the company continues to show the resolve to develop people. “I also urge other industry players, who have generally lagged behind, to play their part in developing skills the industry needs, now and well into the future,” he concludes.

After the recent X.e series agitator unit launch in July 2023, SEW-EURODRIVE South Africa secured an order for nine units earmarked for the mining industry – a world-class first!

SEW-EURODRIVE has an extensive and proven reputation for providing reliable high performance solutions for mixing and agitation applications in various industries globally. Significantly, the X.e agitator units have proven suitable for mixing and blending liquids and other materials in the harsh African operating environment.

“The X.e agitator units are ideal for applications where high power ratings are required for stirring and mixing materials, and what is significant is that we can customise these agitator units to suit the customer’s specifications,” Jarrod Futter, Engineering Manager at SEW-EURODRIVE explains. “For example, we offer various bearing and shafting options and modular systems for the unit which can be selected to meet the customer’s budget and expectations.”

Due to the customer’s requirements for nine low-ratio and moderately high torque and force application, the X3FSM240e HD version was selected. The selection process depends on multiple factors, including the input speed, motor power, loading distance, axial loading and most importantly, the radial loading in the application and required output speed,” Futter adds.

X.e agitator

The X.e agitator differs completely from previous X Series vertical drives. The X.e agitator unit is purpose designed for mixing and agitation, focusing on a stronger and dynamically improved housing. This allows for higher radial load applications, with a maximised bearing distance and an intelligent housing split above the maximum oil level to minimise potential leaks completely and offer better servicing and maintenance capabilities. The X.e agitator also features a new robust, integrated foot design with multiple aligned foot holes to allow for easy mounting and stiffness as well as huge strides in thermal improvement.

During the X.e agitator design process, SEW-EURODRIVE applied the ‘digital-twin’ concept that ties real-world testing to a digital Finite Element Analysis. Explaining the process, Futter says this methodology allows the matching of real-time figures during testing to the digital analysis, achieving the same results. “This enabled many cost benefits, minimised the need for physical testing and allowed the team to see and solve problems before they happened. The digital-twin concept is a more energy efficient and environmentally friendly solution for development and testing, and minimises potential waste,” Futter adds.

As an example, he says that the extended bearing distance could be further optimised along with the oil flow characteristics. Using fluid simulation the piping could be optimised internally, allowing the designers to see how the flow occurs before creating a physical unit to evaluate the theory. The simulation results could then be checked with real-time tests to ensure the oil flow occurs as designed and optimal lubrication is achieved.

The X.e agitator unit has a unique application-specific reinforced and extended bearing distance concept, with the distance between the lower and upper output shaft bearing mounted further apart. This creates a greater shaft distance between these loading points, which allows the low speed shaft to handle higher radial forces. “In layman’s terms – the lever has been made longer to move a larger load,” Futter says.

The X.e agitator unit not only features a pressurised internal lubrication system that allows for continuous oil flow to all upper bearings and gears to ensure the units are well lubricated, but the unique labyrinth seal ensures protection from external particles that may damage the oil seals.

Offering three sizes with various torque ranges and gear units, SEW-EURODRIVE offers client-specific products all safely encapsulated inside the gearbox for client and product protection.

SEW-EURODRIVE is committed to sustainable engineering solutions, and the X.e agitator unit is testament to this. The housing has been developed for easy servicing and maintenance, attributed to sustainable long term use. Therefore, components are easily replaceable. The efficiency gains are attributed to using the X.e series gearing, which has been extensively adapted from the original X- series. Using standard existing components, the X.e agitator series required less design time to achieve the final product.

With five production plants worldwide and a footprint in more than 50 countries, SEW-EURODRIVE offers a quick turnaround in aftersales support and aggressive lead times. “We are looking forward to making history with delivering the first nine X.e agitator units in the world and offering world-class aftersales support,” Futter concludes.
