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.

If the pulp potential was higher than +0.2 V vs. SCE, chalcopyrite did not float either in the PAX or the buffer solution. The flotation behavior of chalcopyrite under controlled pulp potential could be explained as follows.
