The role of biostimulation in iron bioleaching and . - Semantic Scholar

The biostimulation for iron mineral dissolution and reduction with chelators and organic source were investigated on ferrihydrite and quartz sands contaminated with iron minerals. The finding that bacteria can donate electrons to chelators has important implications for the removal of iron impurities from industrial minerals.

Review of Reductive Leaching of Iron by Anaerobic Bacteria .

Leaching of iron, either as an impurity to be removed or as a metal to be recovered, requires a different approach than that of the oxidative leaching that dominates biohydrometallurgy of other metals. In particular, the significant increase in solubility that results from reducing Fe3+ to Fe2+ suggests that a reductive leaching.
