60 Centuries Of Copper: The Flotation Process

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 copperThe process of liberation of copper ores depends upon whether they are oxide or sulfide ores [6] Subsequent steps depend on the nature of the ore containing the copper and what will be extracted For oxide ores a hydrometallurgical liberation process is normally undertaken which uses the soluble nature of the ore minerals to the advantage of
