Inside Copper Mine Concentration Mill Kennicott Alaska 123 Primary Copper Smelting
Aug 01 32 Kennicott also known as and Kennecott Mines is an abandoned copper mining camp in the Valdez Cordova Census Area in the US state of Alaska The footage for this video is taken from my tour of steps include mining concentration roasting smelting converting and finally fire and electrolytic refining Process Description2 4 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

Impacts of Copper on Aquatic Ecosystems and Human HealthCopper Mining and Extraction Sulfide Ores
copper is one of the most toxic metals to aquatic organisms and ecosystems This is just one of the reasons that environ mentally sensitive mining practices are so important Copper is moderately soluble in water and binds easily to sediments and organic matter Bioconcentration which means that the concentration of copper is higherMining 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

Extraction Of Copper Mining Concentration Smelting Copper The Canadian Encyclopedia
Copper Mining The commonest ore used in the extraction of copper is Chalcopyrite CuFeS 2 also known as Copper Pyrites and other such sulfid The percentage of copper in the actual ore is too low for direct extraction of copper to be viable The concentration of ore is required and it is done by the Froth Flotation method Concentration of Ore Jun 23 32 While copper is sometimes found in the native state sulphide minerals such as chalcopyrite CuFeS 2 and bornite Cu 5 FeS 4 are the most important sources of copper in Canada Copper mining operations are established in locations where these minerals exist in sufficient concentration and volume to permit their economic exploitation
