matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and lead.Instead of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 40–45 percent copper along with iron and sulfur, which is then treated by converting in a Bessemer-type converter.

Copper can be produced either pyrometallurgically or hydrometallurgically. The hydrometallurgical route is used only for a very limited amount of the world's copper production and normally only considered in connection to in-situ leaching of copper ores; from an environmental point of view this is a questionable production route.

Uniform, a cost-effective finish produced by a single pass of a No. 80 grit belt.Uniform finishes are less expensive than satin finishes and are suitable for many architectural applications. Hand-rubbed finishes are produced by rubbing with No. 0 pumice and solvent on a fine brass wire brush or a woven, nonabrasive pad. This is a relatively expensive, labor-intensive process.

At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger concentrators has changed to such an extent that comparatively few of the machines in use at the beginning of the period remain in service today.

Copper ore must undergo a complicated refining process to convert it into saleable high-purity copper products, as mined ore typically contains less than 1 percent copper. Copper refining involves increasing the grade and purity of the metal through a variety of physical, mechanical and chemical processes.

Approximately two tons of overburden must be removed along with each ton of copper ore. The ratio of overburden to ore is sometimes as high as 5 to 1. The ore itself averages less than 0.7% copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25% copper.
