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

Copper Mining and Extraction Sulfide Ores

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

How Hydrometallurgy and the SX/EW Process Made

The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In ...

Low grade ores – Smelt, leach or concentrate? -

01/01/2010  In the case of copper, if no additional grinding of the ore is required as the ore grade falls then concentrating and smelting is the preferred route where pyrometallurgical processing can be applied. However, if fine grinding is required (down to 5 μm) then the preferred routes are heap leaching and direct smelting, in that order. In situ leaching is the least preferred processing route ...
