Bioleaching is the metal-extracting practice from sulfides and/or iron-containing ores by means of microorganisms. It is a specified biohydrometallurgical approach in which either the metabolic activities or microbe's products are used to convert insoluble compounds into soluble form, which can then be recovered later [].Biological …

1. Concentration of the ore (removal of unwanted metals and gangue to purify the ore) is done by Froth floatation method as it is a sulphide ore. 2. Roasting: Copper glance (Cu2S) is roasted in the presence of air. Roasting turns copper glance (ore of copper) into copper (I) oxide. 3. Reduction: Copper oxide is then heated in the absence of air.
