With increase in industrialization along with population growth, the demand of metals has dramatically increased and is likely to go up further in years to come.

It necessitates the need for innovative and economical ways of recovering metals from low-grade deposits.

Large stockpiles of low and lean grade ores exist but the recovery of metals from them using conventional techniques is very expensive and leads environmental problem.
Ores with low metal content are not suitable for direct smelting but it is possible to extract metals economically using the activity of microorganisms which decompose a variety of mineral deposit and bring the revolution in mining industry.
