read the restCopper sulfide ores are typically the most profitable types of copper ores to mine That is because they have high copper content and the copper in them can more easily be separated from unwanted minerals However copper oxide ores are more abundant
read the restThe proportion of iron is 100 348 348 304 Roughly the ore may be considered as composed of onethird each of copper sulphur and iron This is the commonest ore of copper but its value depends so much on circumstances other than the percentage of copper contained in it that it is not quoted on the market
read the restSeveral hundred sulfide minerals are known but only five are sufficiently abundant accessory minerals to have been categorized as rock forming Bowles et al 2011 These five are pyrite pyrrhotite galena sphalerite and chalcopyrite and it is the iron sulfides pyrite and pyrrhotite which are dominant
