“…In bioleaching, microbes mediate the leaching of trace elements from soil [1]. The application of Acidithiobacillus bacteria for heavy metals bioleaching from contaminated soil was investigated in recent works [2,3]. Manganese is recovered from its sources by bioleaching, which converts MnO2 into the low valence of Mn compounds [4].…”

Bioleaching can be used for the treatment of toxic elements in sulphide mine-wastes as a newly developed, green and cost-effective technology. The bacterial activity causes the remarkable dissolution of elements compared with chemical methods. Researchers have employed bioleaching for the separation of trace elements from different sources. However, the transfer of toxic elements from contaminated solid wastes to the aquatic ecosystem can be minimized by the production of a biogenic passivation layer. It has resulted in a new perspective of microbial leaching application for the remediation of toxic soils. In this paper, bioleaching-based techniques for a reduction in the environmental pollution of mine tailings were reviewed.
