    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.
