Minerals Special Issue Physical Separation and Enrichment

Physical separation is one the main methods of recovering valuable minerals from an ore (in addition to flotation and hydrometallurgy). Physical separation includes gravity concentration, classification techniques such as hydrocyclones and air classifiers, solidliquid separation (e.g., thickeners and clarifiers), magnetic separation, and electronic sorting.

Concentration Enrichment of Ores, Metals and Non metals

Concentration Enrichment of Ores. At first the ore is crushed to powder. The pulverized ore is separated by physical processes like hydraulic washing, froth floatation, and magnetic separation or by chemical processes, depending on the nature of the ore and its impurities. Concentration of the ore is also known as 'dressing' or 'enrichment' of ore.
