Smelting Simple English Wikipedia, the free encyclopedia
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.
Manufacturing Process of Copper The Balance
Sep 26, 2019· Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between and % copper.
