Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. 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 ...

ASARCO » Milling

The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn't float is called tailings because it goes out the "tail end" of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used.
