Metallic mineral processing typically involves the mining of ore from either open pit or underground mines; the crushing and grinding of ore; the separation of valuable minerals from matrix rock through various concentration steps; and at some operations, the drying, calcining, or pelletizing of concentrates to ease further handling and refining. Figure is a general flow diagram for ...

Direct reduction, in which iron ores are reduced at temperatures below the metal''s melting point, had its origin in such experiments as the WibergSoderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957. Few of these techniques survived, and those that did were extensively modified. Another alternative ironmaking method, smelting reduction, had its forerunners .

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue. The water extracted from the ore by dewatering is ...
