There are many types of copper ore found throughout the world.Picture 4 shows the distribution of these deposits.About 80 of all copper extracted comes from sulphide ores.A typical ore contains only 0.5 to 2.0 copper.It is a measure of the value of copper that it is worth extracting it from such small concentrations.

Copper smelting and classification the smelting of copper copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate.Then, after being smelted, refined copper and copper products are yielded.There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

In addition, huge quantities of copper are known to exist as deep-sea nodules scattered on the ocean floor, although high recovery costs has thus far prevented their commercial exploitation.Chile and the usa are, respectively, the worlds two leading copper-producing nations, chile having overtaken the usa in the early 1990s.
