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.

Ores – metalbearing mineral mass, originated from local clustering of one or more elements. They are defined as utility minerals containing metals in amounts, which can be economically extracted using available technologies. Minerals of ores containing metals to be extracted are denoted ore minerals.

David Duckworth of consulting company Saint Barbara notes that "the issue of higharsenic (highAs) copper concentrates has been highlighted recently with the startup of a number of new projects producing this material. "Copper concentrates can be divided into clean or complex types," he writes in the company's latest newsletter.

The most common and notable example of this are precious metal values (gold, silver etc.) where the beneficiation process is applied directly on runofmine ores followed by the extraction of gold and in some cases silver as a relatively pure metal within the mineral processing circuit.
