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.

Converting: Finally, matte copper is converted into a copper-rich slag, which is then returned to the leaching process and separated from "blister copper," which is sent to another furnace for casting. Waste Generation. Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
