Mineral processing Wikipedia

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.

Apr 01, 2001· Such mills are commonly used in the cement industry but only rarely for mineral processing. Crushed ore and hot gas are fed into the drying chamber of each mill where the moisture content is reduced to 0.5%. Dry ore passes through a diaphragm into the coarse grinding chamber where a charge of 4-inch chrome-steel balls reduces the size to -1/4-inch.
