Process Copper Ore Mining

Copper is extracted in large amounts from the earths crust by mining of sulphide ores and also oxide ores the procedure of copper processing involves mining and transporting oxide ores are generally processed through hydrometallurgy heap leaching solvent extraction and electrowinning the sulfide ores are usually processed using the method of pyrometallurgy froth floatation thickening smelting

Heap leaching is an industrial mining process used to extract precious metals copper uranium and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials

About 80 of all copper extracted comes from sulphide ores a typical ore contains only 05 to 20 copper it is a measure of the value of copper that it is worth extracting it from such small concentrations the ore is a mixture of minerals and rock called gangue the most common copper minerals are

Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation also for some copper ore it is combined by both oxide copper ore and sulfide copper ore after processing test combined processing technologies can also be adopted to extract copper

Copper ore that is rich in sulfides is processed via pyrometallurgy while copper ore that is rich in oxides is refined through hydrometallurgy read on to learn more about copperrefining processes

Tenorm copper mining and production wastes within the united states mining and production of copper are primarily located in the west specifically arizona new mexico utah nevada and montana according to the united states geological survey usgs production in these states and michigan account for more than 99 of domestic copper production

Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining mining produces ores with less than 1 percent copper concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper

Processing of copper ore the first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces this is accomplished by a variety of subsequent processing steps

Different methods are used to process copper sulfide ores depending on the concentration of copper within the 11 responses to copper ore types sulfides vs oxides copper mining in

Copper ore types oxides the copper sulfate solution called the pregnant leach solution is then stripped of copper via a solvent extraction and electrowinning sxew process alternatively the copper can be precipitated out of the pregnant leach solution through a process called cementation whereby the copper is contacted with scrap iron

A look at the underground mining process the resolution copper deposit lies more than a mile beneath the surface the most viable way to recover this ore body is by going underground using a process called block caving block caving is a proven mining method using advanced technologies heres how it works ore rock containing continued
