How Copper is Mined and Refined: "A Story Of Copper" 1951

The copper is refined by electrolysis. The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid. Cathodes are thin rolled sheets of highly pure copper or, more commonly these days, reusable stainless steel starting sheets (as in the IsaKidd process).

Copper mining and the copper extraction process explained

Although copper is widely distributed in the earth’s crust, for it to be mined as commercially exploitable deposits, it need s to contain at least 0.5% copper and preferably 2% or more. The known reserves of high-grade ore would produce around 1 billion tons of copper, which at current consumption levels represents a 65 year supply.

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.
