Copper Mining and Extraction Sulfide Ores
This is not enough to make it commercially viable to extract the rock Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (05% by mass) Ideally, the figure should be closer to 2% The world’s largest copper ore deposits are found inCopper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the differentCopper Mining and Processing: Processing of Copper Ores
Eliminating Copper from Gold Ore
When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidationPreliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copperthe gold Copper extraction is accomplished by leaching (1) Copper ore is pulverized and saturated with sulfuric acid (pyrite helps) (2) The copper sulfate solution is mixed with tin (cans), causing precipitation of native copper, then sent to blast furnace for purification (3) Copper ore needs sulfides for roasting (mix ofcopper ore and gold extraction mensennetwerknl
