What's Happening?
Sigma, a high-performance abrasives supplier, has launched a next-generation Dense Media Separation (DMS) ferrosilicon platform in South Africa. The platform is designed to meet the growing demand for stable and high-performance ferrosilicon supply, crucial
for beneficiation and diamond recovery operations worldwide. Sigma operates from a modern 10,000 m² integrated manufacturing facility in Gauteng, combining milled and water-atomised production under rigorous quality control. The facility boasts capacities of 53,000 t/y induction melting, 25,000 t/y milled ferrosilicon, and 15,000 t/y atomisation line, ensuring consistent high-density supply. Sigma's production philosophy focuses on purity, process control, and consistency, producing ferrosilicon exclusively from Blue Steel and 75% ferrosilicon feedstock. The company also operates a dedicated in-house research and development facility and analytical laboratory to drive continuous improvement.
Why It's Important?
The launch of Sigma's advanced DMS ferrosilicon platform is significant for the global mining industry, particularly in beneficiation and diamond recovery sectors. As global capacity tightens and compliance pressures increase, Sigma's platform offers a reliable and scalable solution to meet market demands. The company's focus on purity and consistency ensures efficient media circulation and optimized plant recovery, which are critical for operational success. Sigma's expansion into international markets across Africa, Europe, and Asia positions it as a strategic global partner, offering assured performance and long-term supply stability. This development addresses market instability and compliance lapses among key suppliers, reinforcing confidence and continuity in the industry.
