The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. ... There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores.
