  • Extraction Of Copper | Mining, Concentration, Smelting

    Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides 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 ofPart of an interactive online booklet about copper mining explaining the chemical reactions used to purify copper page 4: Chemical reactions : At this stage of the process, the chemical reactions begin They convert the copper minerals into copper metal We can illustrate the types of process using the example of chalcopyrite CuFeS 2 From the formula, it is clear that iron and sulphurCopper mining Chemical reactionsMining 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 yearCopper Mining and Extraction Sulfide Ores

  • How we’re making copper mining in Latin America more

    · Adjusting the reagent chemistry to local conditions and specificities is a crucial part of ensuring the economic sustainability of a mine “Ores across Latin America have a higher concentration of nitrates than elsewhere in the world,” explains Rodrigo Zambra, Regional Sales Director Latam at Solvay “Nitrates degrade metal extractants Mines therefore need a nitrateresistant productThe chemistry of mine water is dependent on the geochemistry of the ore body and the surrounding area Water exposed to sulfurbearing minerals in an oxidizing environment, such as an open pit or underground workings, may become acidified This potential is greatly dependent on sitespecific factors Sludge Sludge is the semisolid gelatinous materials (ie, soft mud, slime, slush, or mireCopper production & environmental impact· In 1995, Canadian mine production of copper totalled 729 million kg Canada's annual mine production of copper exceeds 600 000 t and refined copper production is over 500 000 t Canada is the fifthlargest mine producer of copper in the world Most of the copper concentrate from mines in eastern Canada is converted to copper metal (99% pure) at smelters located at Flin Flon, Man,Copper | The Canadian Encyclopedia
