The Use Of Microbes In Mineral Mining

Mining With Microbes C&EN

Oct 15, 2012Instead of separating the metal from the pyrite with high temperatures or pressures, biomining uses microbes from the Acidithiobacillus and Leptospirillum genera to do the job. These microbes have protein systems that can oxidize Fe 2+ to Fe 3+, which they use to generate chemical energy for their metabolic processes, Dold says.

Microbes have a variety of properties that can effect changes in metal speciation, toxicity and mobility, as well as mineral formation or mineral dissolution or deterioration. Such mechanisms are important components of natural biogeochemical cycles for metals as well as associated elements in biomass, soil, rocks and minerals, e.g. sulfur and

In the ‘indirect mechanism’ represented by,, the mineral is leached only by the ferric ions, whereas in the ‘direct mechanism’, the mineral is not leached by ferric ions, but by some biological agent.Because bacteria readily attach to
