Bioleaching has been successfully used in commercial metal mining for decades. It uses
microbes to biosolubilize metal-containing inorganic compounds such as metal oxides and …

A serious environmental problem is associated with the accumulation of solid waste on the
Earth. Researchers are encouraged to find an efficient and sustainable method to recover …

Improving the bioleaching efficiency of metals from spent mobile phone printed circuit
boards (PCBs) in a short time has been of major interest in recent years. In this paper, a …

Background Enormous amounts of gold mine tailings (GMT) are produced as a result of
mineral activities, but these mine tailings produced from previous ore processing still contain …

Spent-medium bioleaching of V and Ni from a power plant residual ash (PPR ash) was
conducted using organic acids produced by Aspergillus niger. The production of organic …

The present study evaluated the potential of Bacillus megaterium as a cyanogenic bacterium
to produce cyanide for solubilization of platinum and rhenium from a spent refinery catalyst …

This study presents bioleaching of metals from a vanadium-rich oil-fired ash (OFA) sample
using adapted Acidithiobacillus ferrooxidans. OFA is a major by-product of thermal power …

The presented review is based on scientific microbiological articles and patents in the field
of biomining valuable metals. The main attention is paid to publications of the last two …

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

In this attempt recovery of heavy metals from a hydrocracking spent catalyst was studied in a
slurry bubble column bioreactor using Acidithiobacillus thiooxidans. Firstly adaptation of …
