Copper Concentrate an overview | ScienceDirect Topics

The pulp from this grinding process is introduced into a floating process to which water and chemical reactants are added. This process results in a collective concentrate, CuMo, containing approximately 30% copper and 1% molybdenum. In a followup process, the copper and sulfurmolybdenum concentrate are separated.

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
