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 ...

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...
