Primary production from mined lead ore is of course the original source of all lead, but secondary production, where it is recovered from recycled products or from residues arising from the production process is of enormous importance. Secondary lead production now accounts for more than half of all lead produced throughout the world.
The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2.
