The copper processing industry refines copper from metal ores or scrap copper. The leading consumers of copper are wire mills and brass mills, which use the copper to produce copper wire and copper alloys, respectively.
Free-machining copper has an addition of around 0.5% of sulfur or tellurium which raises the machinability rating of copper from a value of 20 to 90 (based on a scale of 100 headed by free-cutting brass, UNS C36000).
Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling ...

Acids are introduced to copper-bearing ore, seeping through and dissolving copper and any other metals, including radionuclides. The liquid that "leaches" through the rocks is collected. This liquid contains the dissolved copper, known as a pregnant leach solution (PLS).
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Solvent extraction is generally not used to treat in organics (acids, bases, salts, heavy metals). Solvent extraction processes are not designed to treat particular compounds, and extraction efficiencies and processing rates are lower when there are high concentrations of indigenous organic compounds (humic and tannic acids in soil).
