Processing and transporting coal happens in harsh operating conditions. This is largely due to the presence of fine coal particles, called duff, and their corrosive impact on mechanical parts.

This means that it’s essential to use lubricants designed to repel duff and dirt to protect equipment at all stages across the coal-handling ecosystem. Gavin Ford, National Marketing Manager at Lubrication Engineers (LE) South Africa says that coal industry operators should take a two-pronged approach by using high-quality lubricants, applied in the right quantities and at the necessary intervals, in conjunction with key maintenance techniques.

“Along with fine particles, heavy loads, shocks and jars are typical of coal operations and lubricants designed to withstand these conditions are essential to ensure maximum efficiency; but these do need to be paired with making sure that key components are cleaned well before a lubricant is applied,” says Ford.

As duff is by nature extremely fine and pervasive, managing contamination in components like gear teeth surfaces, fill pipes, grease fittings and plugs need to get special attention in coal-processing environments. Correct storage of lubrication supplies is also important, so that foreign matter is not re-introduced when lubricants are applied.

In bulk materials handling applications, the uncontrolled discharge from conventional chutes can lead to increased maintenance and replacement costs, as well as decreased productivity.

Recognising these challenges, companies around the world, both large and small, have adopted Weba Chute Systems, a choice which represents a shift towards greater efficiency and less downtime. Mark Baller, CEO of Weba Chute Systems, explains that there is a growing consensus across the globe that incorporating custom-engineered transfer chutes is paramount.

“There are still some that overlook the significance of transfer points that are engineered for specific application requirements, ranking them below screens, crushers or feeders in the process hierarchy. Baller points out a critical misconception that undermines operational efficiency: the notion that initial savings from inexpensive inferior chutes outweigh long term costs.” This approach is flawed, “he argues,” “as it inevitably leads to higher operational expenditure due to frequent maintenance, and in some cases unscheduled downtime.”

Highlighting the benefits of custom-designed solutions, Baller notes, “Proper initial design significantly lowers maintenance needs, improves material transfer, extends conveyor belt lifespan and boosts throughput. Moreover, our chutes are engineered to minimise environmental impact, reducing airborne dust and enhancing workplace health and safety.”

With South Africa’s winter season on its way, many concrete users will know that slower curing times could derail their contract or production schedules, but accelerating admixtures – or accelerators – are available to solve this challenge.

With the country’s generally temperate climate, it is easy to forget that many provinces and neighbouring Lesotho regularly experience sub-zero temperatures, points out Hannes Engelbrecht, Concrete Business Unit Director for Domestic and Sub Saharan Africa (SSA) at CHRYSO Southern Africa. Temperatures do not even need to reach freezing point; the concrete hydration process slows down steadily as temperature drops and actually stops when it goes below about 5 degrees Celsius.

A significant amount of current concrete construction – especially for wind turbine bases and foundations for solar photovoltaic infrastructure – is, in fact, taking place in provinces like the Northern Cape and Eastern Cape where temperatures fluctuate widely. Efficient stripping time of formwork is crucial in allowing these projects to meet their stringent deadlines to complete construction and start delivering renewable energy.

Precast products

“Low temperatures create a range of problems for contractors and concrete product manufacturers,” says Engelbrecht. “Most projects in today’s world need to be delivered on a fast track basis, so there is no room for slow concrete curing to hold up the schedule. Similar constraints apply in the manufacture of precast products, where production must simply keep up with customer orders and delivery deadlines.”

Last year NSDV announced a 70% women-led legal team. This year the firm appointed another three women and is happy to announce that it has kept it’s 70% women-led position in a male-dominated industry.

“We attract a lot of women because of how different the firm is. ‘People over Paper’ – our unofficial mantra – captures our preferred relationships with all stakeholders within the industries which we work. From unions to communities to the DMRE; we simple enjoy being relational vs transactional. I think women want to be part of a brand of law that is known for this contemporary approach,” says Lili Nupen Co-founder and Director of the Mining and Environmental Law Departments at NSDV.

The three new appointments are in keeping with President Ramaphosa’s sentiments that mining has untapped potential for the continent (including female talent). According to his address at Investing In Mining Indaba 2024, “Africa has the potential to be the fulcrum of the global energy transition with Mining at it’s core.”

“We’re seeing a massive boom in renewable energy, construction, and environmental needs at mines. It’s so exciting to see the growth in the sector and to be a part of it. As the industry expands, so do we and employing the right team is critical for us to maintain our culture of approachability paired with expert advice and experience,” says Nupen.

Nigeria has recently taken a significant step in its ongoing efforts to reform the mining sector by inaugurating 350 new operatives into its mining marshals. This move underscores the federal government’s dedication to combating illegal mining and improving the operational effectiveness of the mining sector.

With the addition of these 350 new operatives, the total number of mining marshals deployed nationwide now stands at 2,570. The inauguration ceremony took place at the Nigeria Security and Civil Defence Corps (NSCDC) headquarters during a Passing Out Parade. Dr. Dele Alake, the Minister of Solid Minerals Development, was represented by the Permanent Secretary, Dr. Mary Ogbe.

Dr. Alake commended the collaborative efforts between the Ministry of Solid Minerals Development and the Ministry of Interior. He specifically acknowledged the contributions of Dr. Olubunmi Tunji-Ojo and the NSCDC in addressing the challenges posed by illegal mining activities.

Reforming the mining sector

Dr. Alake highlighted the achievements of the mining marshals. He noted that their efforts have notably reduced illegal mineral haulage and the activities of unlicensed operators across the country. The initiative to strengthen the mining marshals began with the inauguration of the first batch of 2,220 operatives. Since then, significant progress has been made, including the arrest of over 200 illegal mining suspects, with 133 prosecutions currently in progress. Additionally, confiscated illegally mined minerals have been forfeited to the federal government.

Pasofino Gold Limited has completed drilling works at the Bukon Jedeh ‘gold camp’ within the Company’s Dugbe Gold Project, Liberia.

Warren Greenslade, Pasofino Interim CEO made the announcement and credited the smooth operation was as a result good relationships with local communities. He expressed optimism about the visual results and the potential for high-grade gold based on existing evidence.

Bukon Jedeh

The Bukon Jedeh area has been a significant site for gold production in Liberia for decades, mainly through informal mining. Past exploration by Equator Resources Limited in 2012 included reverse circulation (RC) drilling but did not cover the most productive pits developed afterward.

The program involved drilling 11 holes totaling 1,328 meters across a 4 km long area, targeting key mining sites, historic drill intersections, and new promising intervals identified by sulphide mineral abundance.

The third phase construction of concentrator at the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo (DRC) has been finished.

Ivanhoe Mines made the announcement and said the development occurred ahead of schedule and within budget, with the initial ore introduced to the new concentrator, and the first concentrate production expected next month. The ramp-up to commercial production is targeted for the third quarter of this year.

The Phase 3 concentrator is designed to process ore from Kamoa 1, Kamoa 2, and the Kansoko underground mines. Once fully operational, it will position Kamoa-Kakula as the world’s fourth-largest copper mining complex and the largest in Africa. By April 30, 2024, Ivanhoe Mines had accumulated 2.25 million tonnes (mt) of ore with a copper grade of 3.1% in surface stockpiles.

Scope of work

Commissioning of the Phase 3 concentrator began with dry commissioning last month, followed by wet commissioning on May 26. The new concentrator’s output, characterized by higher sulphuric content, will reduce the external energy needed for the smelter. About 70,000 tonnes (t) of this concentrate will be stockpiled in preparation for the smelter’s start-up. The completion of the Phase 3 concentrator is expected to increase the complex’s annual copper production to over 600,000 tonnes by the third quarter of 2024.
