Mine dewatering - QueensMineDesignWiki

Mine dewatering is a production critical function; inflow of waters needs to be removed to maintain a safe production environment. In order to ensure redundancy, the pumping system must include spare pumps and parts. In a three-unit system, any two pumps need to be able to provide the maximum inflow.

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.
