Mineral Processing and Metallurgical Testing

SRC’s Mineral Processing team provides leading‐edge research, development and demonstration services for a variety of commodities and mineral processing
technologies. We help maximize your resource and improve productivity at every stage of the mining cycle, from exploration to closure. 

Our team of engineers and scientists can customize testing and design to meet the unique needs of mining companies in diamonds, uranium, potash, lithium, base metals, precious metals, rare earth elements and industrial minerals.
