The simplest case may be represented by a low grade copper ore which in its natural state could not be economically shipped or smelted. The treatment of such an ore by flotation or some other process of concentration has this purpose: to concentrate the copper into as small a bulk as possible without losing too much of the copper in doing so.

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.

The copper crown is likely to be held by Chile in the future, as well. According to Cochilco, between 2000-2015 about 35 copper deposits and three gold deposits were discovered in central-north Chile. They increased the country’s resources by 208.6 million tons of copper and 34.3 million oz of gold.

Copper ore enrichment involves mechanical processing which enables an effective management of the extracted ore. As a result, the concentrate contains the amount of copper that can be processed further in a smelter. This process is necessary due to an average 1.52% content of copper in the exploited Polish deposits.
