Mining screens, classification and separation are integral to ore processing, metals and minerals extraction, and controlling the final product quality in any mining and processing operation. Adopting efficient screening and separation solutions can increase yield and productivity while reducing environmental impact and minimising ore processing costs.
Miners require rugged, durable and custom-designed screening, vibration and separation equipment that are not only high-performing, energy-efficient, cost-effective but require less maintenance.

Mining separation technology trends
Physical separation techniques used in mining include screening, sorting, classification, floatation, dewatering, thickening, gravity separation, centrifugal separation, washing, filtering, drying, and flocculation. While most physical separation processes involve water, electrostatic and electrodynamic separation, dry magnetic separation, air tabling, air elutriation, dry cycloning, and mechanised sorting are some of the physical separations conducted on dry feeds.
The mining separation technologies based on hydrometallurgy and chemical processing include heap-leaching, dump-leaching, in-situ leaching, selective leaching, bioleaching, as well as high-temperature and high-pressure leaching with ultra-fine grinding to optimise leaching kinetics and metal recovery. Whereas the technologies used for solution purification and concentration include precipitation, ion exchange, solvent extraction, membrane transfer, and electrowinning.
Research and development in mining separation technologies are focused on maximising efficiency, precision and speed while reducing environmental impact. The key trends in the field have been to achieve greater conversion efficiency, limit the usage of water and toxic chemicals, automate separation using advanced sensors, modelling and simulation, and increasing adoption of pressure leaching, and magnetic and membrane separation technologies for optimal performance and environmental benefits.
