Abstract Hexavalent chromium (Cr (VI)) in water is a proven carcinogen to different internal
and external organs of the living organisms. There are different human activities …

Heavy metal pollution is a direct consequence of the extensive utilization of heavy metals in
various industrial processes. The persistence and nondegradability of heavy metals cause …

Large quantities of solid catalysts are routinely used in many chemical industries especially
in petroleum refining and petrochemical industries. Solid catalysts contain metals, metal …

Bioleaching of copper-rich electronic waste material was carried out using mesophillic
Acidithiobacillus thiooxidans. The leaching behaviour of copper was investigated using …

The study proposes the use of microbial fuel cell (MFC) technology to reduce toxic Cr (VI)
present in industrial wastewater to less toxic trivalent chromium [Cr (III)], while generating …

Research on biohydrometallurgy of secondary metal resources is primarily focused on the
leaching of valuable metals. For secondary metal resources biological processing can be an …

The by-products of zinc refineries are used as the primary mineral resources for the
commercial production of indium. The discarded LCDs containing adequate amount of …

Highlights•Moderately thermophiles were adapted in increasing PPCBs density causing
improved tolerance and efficient copper recovery.•Community structure was relatively simple …

This review examines the status of bioleaching technology in recovering valuable metals
from electronic waste (e-waste). Bioleaching of e-waste is reviewed with emphasis on the …

This study determined the optimal conditions required to attain maximum metal recovery in
the bioleaching process of dewatered metal-plating sludge using Acidithiobacillus …
