Copper processing Ores Britannica

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.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors..

Liberating Disseminated Bulk Ores Mineral Processing

If the minerals themselves have, say, a copper content of 30%, then the grade of ore would be about 0.9% Cu. The ore minerals in the matrix must be liberated from the gangue. This requires crushing and grinding the ore down to a particle size where discrete particles consist approximately of either pure mineral or pure gangue, which can then be
