ABB has implemented advanced controller technology for high-power rectifier systems at the Manganese Metal Company refinery in Mbombela, strengthening power stability at the facility

Located in South Africa’s Mpumalanga province, MMC holds a unique position in global markets as the only producer of high-grade electrolytic manganese metal outside China. It is also the world’s largest refinery of 99.9% selenium-free EMM. The company supplies more than 120 customers across 20 countries, with approximately 95% of its annual output exported for applications such as lithium-ion battery production, alloying, welding and electronics.

To safeguard operational continuity in a competitive international environment, MMC required a solution to counter power instability that had been placing strain on ageing transformers. ABB addressed this challenge by integrating its AC 800PEC high-performance controller with six MCR1000 high-power rectifier units. The controller is engineered for rapid and accurate responses to grid fluctuations, supporting high-speed control algorithms with cycle times as low as 100 microseconds for fast control loops.

The upgraded system is designed to ensure a more stable power flow to the manganese production plant, enhancing availability and supporting higher productivity levels. According to the customer, the advanced control platform has significantly reduced unplanned outages and improved overall operational reliability, resulting in more predictable production performance.

“We were faced with several critical challenges that affected our operations and potentially our market position,” said Teheli Morabe, chief operating officer, MMC.

“Technical constraints, particularly the use of older rectifier technology, resulted in trips whenever there was adverse weather and during electrical grid fluctuations. The plant’s continuous production demands meant that downtime was not an option, and so we had to resolve these issues without disrupting operations. ABB’s innovations not only addressed our immediate operational challenges but also established a foundation for long-term stability and competitiveness.”

“Our project with MMC is an example of ABB working in an unseen way yet making a significant positive impact to important customer operations,” said Ralph Burgener, Global Business Unit Manager for High-Power Rectifier, ABB’s Process Industries division.

“Power supply challenges exist the world over but are particularly well-known in South Africa. To be able to overcome that with automated, power control technologies brings a great deal of satisfaction to our teams as engineers. We are enabling this manganese plant to compete internationally, which aligns with ABB’s mission of engineered to outrun.”

Caterpillar launches the new Cat 707 wide body truck.

Construction

Engineered for durability and high machine availability, the new Cat 707 wide body truck is built around a fully integrated Cat powertrain that combines a Cat C13 engine, Cat automatic transmission, and proprietary Cat axles

Designed to handle demanding haulage applications, the truck offers a maximum payload of 66 tonnes and is available in standard or heavy duty configurations, with body options of 40 m3 or 42 m3 to suit varying materials and site conditions.

Developed with Caterpillar’s rebuild focused design philosophy, the 707 wide body truck is intended to deliver consistent mechanical availability throughout its operating life while supporting a second lifecycle through cost effective rebuilds. This approach helps customers extend asset life and manage long term operating costs.

The new 707 wide body truck has been engineered, manufactured, and field tested using the latest technologies to ensure it is ready for work upon deployment. It is the first model in a new wide body truck product family that expands Caterpillar’s hauling systems portfolio.

“We have engineered our new wide body truck with a unique philosophy – it’s built to be rebuilt, offering consistent mechanical availability and longevity through a second lifecycle, which can help lower operating costs.” Angel Gonzalez, global product specialist at Caterpillar.

Performance and lifecycle efficiency

The Cat 707 can be configured with a 400 kW Cat C13B engine that meets China Nonroad Stage IV emissions standards, or a 358 kW Cat C13 engine that delivers U.S. EPA Tier 3 equivalent emissions. Both engine options are equipped with a high rated standard engine brake. Power is delivered through a six speed automatic transmission, with an optional integrated hydraulic retarder available for additional braking control.

To support reliability and uptime, the truck features proprietary Cat axles, integrated Cat powertrain controllers, and Cat designed wiring and electrical harnesses. Three levels of braking and retardation are available, including the engine brake, optional hydraulic retarder, and service and parking brakes. This combination improves downhill loaded control, enhances safety, and supports faster haul cycles.

The 707 wide body truck is designed for effective pass matching with Cat 986, 988, and 988 XE wheel loaders, as well as Cat 350, 374, and 395 excavators, helping to improve site productivity.

Operator comfort and training are supported through a left side operator seat and an optional right side instructor seat. The cab is mounted on a robust four point system and includes a standard falling object protective structure, with an optional rollover protective structure available. A reversing camera can be specified to improve maneuvering safety. Automatic shifting with simplified gear selection helps increase efficiency, while the hoist system delivers fast 20 second raise and lower cycle times to speed up material unloading.

Low operating and maintenance costs are supported by the integrated Cat powertrain mounted on a reinforced chassis. When combined with Cat Customer Value Agreements, customers can achieve higher uptime while maintaining reliable performance across multiple life cycles. Grouped service points reduce maintenance time, while a ground level engine shut off switch allows safe engine shutdown by stopping fuel delivery.

Mining

Sandvik Rock Processing has finalised a comprehensive OEM-level refurbishment of a Sandvik BR3288i hydraulic breaker and a Sandvik BB8094R breaker boom for a leading gold mining operation in Ghana

The project restored a key component of the site’s primary crushing circuit, with the rebuild, reinstallation and commissioning delivering measurable gains in equipment availability and output. Ongoing quarterly inspections and technical support from the company’s Kumasi-based team continue to reinforce performance.

The refurbishment was carried out at Sandvik Rock Processing’s fully equipped workshop in Kumasi. The breaker and boom assembly are installed at the mine’s run-of-mine grizzly, where oversized rocks generated during blasting are reduced to prevent blockages and maintain smooth material flow into the crusher.

“This project restored a vital asset that plays a central role in the mine’s primary crushing circuit,” commented Amos Fordjour, senior service technician at Sandvik Rock Processing. “Our extensive rebuild has returned the machine to OEM performance standards, significantly improving the mine’s reliability and production continuity.”

After more than five years in operation, the equipment was scheduled for refurbishment. Work commenced on site, where the 11 tonne boom assembly was dismantled using the mine’s crane infrastructure before being transported over a three-hour journey to the Kumasi workshop.

“Once in the workshop, our technicians stripped the units completely - checking for critical components such as pins, bushings, cylinder seals and mounting brackets that required replacement,” remarked Fordjour. “The boom was sandblasted and inspected for cracks, the hydraulic cylinders were rebuilt and pressure-tested and the hammer was fully refurbished.”

Haqq Abdul Rahman, graduate technician at Sandvik Rock Processing, highlighted the importance of parts availability in reducing turnaround times. He explained that mines frequently face challenges with oversized rocks at the run-of-mine grizzly, and temporary mobile breakers often require considerably more time to handle the material.

“It was important that we controlled the turnaround time on this project so the mine could put the equipment back to work as soon as possible,” said Rahman. “This particular unit breaks oversized rocks much faster than the smaller mobile units that the mine had to rely on while this one was being refurbished.”

The Sandvik BB8094R breaker boom, rated at 55 kW input power, provides a maximum reach of 12.7 m, with nominal horizontal and vertical reaches of 9.8 m and 9 m respectively, and a full 360° swing capability. The 2.3 tonne Sandvik BR3288i hydraulic breaker incorporates an operating principle that optimises stroke length, blow energy and includes an idle blow protector, enabling adaptability across applications while enhancing hydraulic efficiency and operational safety.

Fordjour underscored the role of strict quality control procedures throughout the refurbishment.

“We follow strict operating procedures and standards in everything we do,” continued Rahman. “This includes using only genuine Sandvik parts which allows us to guarantee the quality of both the components and the workmanship.”

Following workshop completion, Sandvik Rock Processing teams returned to site for installation and commissioning. The three-week process required detailed coordination around crane usage, electrical integration, positioning and safety compliance.

“We work very closely with customers during removal, installation and commissioning,” Fordjour noted. “In this case, the mine provided the cranes and support equipment and we handled all the technical work; that collaboration is critical.”

Rahman explained that the restored boom and breaker now offer enhanced structural integrity, precise OEM clearances and improved swing performance, supporting efficient energy transfer and high twist resistance under demanding impact conditions.

“For the mine, the biggest impact is uptime and production,” said Rahman. “Without this breaker, their crushing circuit slows down considerably; now that it is back to full performance and production is consistent again.”

Post-commissioning support remains ongoing, with Sandvik Rock Processing conducting quarterly inspections to assess pins, seals and overall structural condition, while maintaining readiness for service interventions whenever required.

The countries of sub-Saharan Africa are set to become more important as the global economy realigns in the face of wider geopolitical shifts, a new report suggests

South Africa, as one of the so-called BRICS nations, also stands to prosper.

The report, by Boston Consulting Group, suggests that global trade will show some resilience, and could grow 2.5% annually through to 2034 despite rising fragmentation.

According to the report, nations in the so-called ‘Rest of the world’ category — which includes all of sub-Saharan Africa, with the exception of South Africa — look set to gain overall on the back of strategic neutrality.

“These free agents, however, will become increasingly important in the future, both as markets and suppliers of goods and services,” the report notes.

While there are a wide range of trade scenarios, reflecting current volatility, small non-aligned countries appear to be relatively isolated from any potential negative fallout.

The BRICS+ nations — including South Africa, and countries that joined later, such as Egypt and Ethiopia — will also seek to expand relationships within the Global South.

“BRICS+ countries have been taking steps to collaborate with each other on trade, which they see as a driver of growth,” the report notes. But their approach to trade differs, with some negotiating deals with other groupings and some not.”

BRICS+ nations (excluding China) could see 3% growth with the rest of the world over the period as well as trade growth among themselves, it adds.

“Global trade isn’t retreating, it’s reorganising,” said Marc Gilbert, managing director and senior partner, Global Leader of the Center for Geopolitics, and a co-author of the report.

“Leaders who embed geopolitics in capital and strategic decision-making will be best positioned to navigate the next decade of change to secure resilience as well as growth.”
