Ore Mineral - an overview ScienceDirect Topics

The prime commodity is the principal ore mineral recovered from mines. Associated commodities are the associated minerals recovered as by-products along with the main mineral. All ore deposits contain a number of valuable trace elements that can be recovered during processing of ore. The prime commodity of a zinc-lead-copper-silver mine is zinc

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.
