Microorganisms are used in largescale heap or tank aeration processes for the commercial extraction of a variety of metals from their ores or concentrates. These include copper, cobalt, gold and, in the past, uranium. The metal solubilization processes are considered to be largely chemical with the microorganisms providing the chemicals and the space (exopolysaccharide layer) where the

Copper extraction by wet chemical method

Copper extraction by wet chemical method

Currently the extraction of copper is performed using a pyrometallurgical process that involves the use of electricity as well as coal, both of which are expensive. The use of fossil fuels in extraction produces carbon dioxide which contributes to global warming. The other method used is solvent extraction followed by electrowinning (SXEW).

Copper extraction

Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper

Extraction of cobalt and copper can reach 96.51% and 26.32%, respectively, after direct bioleaching for four days at 10% pulp density. The copper is also found enriched in the residue after the bioleaching process. The copper grade in the leaching residue is above 20%, thus it can be returned to the smelting process to recover remaining copper.
