    Copper ores are characterized by a low copper content. For this reason, the finely ground ore undergoes concentration prior to smelting. This process involves the separation of the valuable minerals from the bulk of the gangue (worthless rock) to give a number of commercial concentrates (for example, copper, zinc, pyrites) and tailings.

    Smelting is the general term for getting a metal from its natural ore. Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.

    Hand tool - Hand tool - Smelting: Perhaps 1,000 years after humans learned about melting copper, they found that still another stone, a brittle one directly useless for tools, would produce liquid copper if sufficiently heated while in contact with charcoal. This step was epoch making, for it was the discovery of smelting, or the separation of a metal from a chemical compound called ore.
