  • Copper mining. The main stages.

    Copper mining There are a number of steps to get nearly pure copper from copper ore. Roll your cursor over the steps in the diagram to see a summary of each one. Click to find out more. Mining: The ore is removed from the ground in either open pit or underground mines. The ore : An ore is a rock that contains enough metal to make it worthwhile extracting. The main copper ores are: chalcopyrite

    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

    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. The main ores of copper are sulfides and oxides. From their chemical formulas

    How copper is made material, used, processing, steps

    Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of high-grade copper ore around Lake Superior began. The development of more efficient processing techniques in the late-1800s allowed the mining of lower-grade copper ores from huge open-pit mines in the western United States.
