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 ....
situ leaching of copper ores; from an environmen-tal point of view, this is a questionable produc-tion route Several different processes can be used for copper production The traditional process is based on roasting, smelting in reverbatory fur-naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con-...

Open pit mining is the most widely used technique of mining copper today It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface Underground mining is used when the copper ore is not near the earth's surface Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or ....
Sulfidic copper ores are too dilute for direct smelting Smelting these materials would require too much energy and very large furnace capaciti The copper ore coming from the mine (05 – 1 % Cu) must be concentrated by beneficiation The valuable minerals like chalcopyrite are intergrown with gangue...
