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 ore is removed from the ground in either open pit or underground mines. underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. open-pit 90 of ore is mined using the open pit method. ores near the surface can be quarried after removal of the surface layers. the ore
Processes. copper is found in natural ore deposits around the world. this page explains the production route taken from extraction of ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
The copper ore enrichment process is a mechanical process of recovering ore before it undergoes smelting. it is composed of four main stages mined ore crushing, milling, flotation and drying. the crushing process prepares fresh ore 1.3 of pure copper from copper mine to milling process. at this stage, ore is screened on two main fractions ...
