The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
These wastes can be subdivided into a number of categories: waste rock, mill tailings, coal refuse, wash slimes, and spent oil shale. The mining and processing of mineral ores results in the production of large quantities of residual wastes that are for the most part earth or rocklike in nature.

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of lowgrade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper .
Coal is the most important sector and accounts for 24 percent of total mining production, followed by PGMs (23 percent); gold (16 percent); iron ore (12 percent); other nonmetallic minerals (6 percent); diamonds (4 percent); manganese ore and chromium ore (3 percent each); other metallic minerals, building materials and nickel (2 percent each), and copper (1 percent).
Some ore types can be treated by crushing, grinding and mixing ore with water to produce slurry. The coppercontaining particles are then removed by a process called flotation. The product of this process is dry, gray powder called copper concentrate, which contains about 30 percent copper.
A typical ore contains only % to % copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue ).
