May 07 2021 The method used to extract copper from its ores depends on the nature of the ore Sulfide ores such as chalcopyrite CuFeS2 are converted to copper by a different method from silicate carbonate or sulfate ores Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper Answer The second step in the extraction of copper from its ore depends on the process being used designed based on the ore type For example the process for oxide copper ore will be different from that for sulphide copper ore The oxide ore may need to be leached directly while the sulphide co
