Copper and manganese selectively leached from the material in the absence of SMBS thereby leaving out cobalt, nickel, and iron. However, all elements, (Cu, Co, Ni, Mn, and Fe) leached out in the presence of SMBS. The overall recoveries of copper, cobalt, nickel, manganese, and iron were dependent on pH and amount of sodium metabisulphite.

Siderite FeCO3 Extraction of Iron A mixture of oxide ores of iron (Fe3O4 and Fe2O3) is used to extract pure iron. Concentrating the ores Jaw crushers are used, and the ore is broken into smaller pieces. Concentration is carried out by the gravity separation process. Clay, sand, etc., are removed by washing it with water.

The concentrated ores can be converted into metal oxide by using calcination or roasting based on the nature of the ore. The process of heating carbonate ore strongly in the absence of air is called calcination. Metals such as zinc (Zn), tin (Sn), lead (Pb), and iron (Fe) can be extracted by the process of calcination.
