Copper Mining and Production Processes Explained

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

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.
