These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals called gangue

Read MoreThe process of extraction of metal from the concentrated ore depends upon the nature of the ore as well as the nature of impurities present in the ore. Before the concentrated ore is subjected to final metallurgical operations in order to get the metal in the free state the preliminary chemical treatment may be
Read MoreBismuth extraction Brife introduction Bismuth is extracted from its ores by dry wet or electro-metallurgical methods the choice depending upon the composition of the ore and economic conditions. The dry process is more frequently practised due to the easy reducibility of the oxide and sulphide together with the low melting-point of the metal which renders it possible to effect a
