Ore Wikipedia

Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble metals (not usually forming compounds) such as gold. The ores must be processed to extract the elements of interest from the waste rock and from the ore

Processing of Nickel Laterite Ores on the Rise feeco

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.
