microbes. The role of the bacteria is the fur-ther oxidation of the ore, but also the regeneration of the chemical oxidant Fe3+ from Fe2+. For ex-ample, bacteria catalyse the break-down of the mineral pyrite (FeS2) by oxidising the sulfur and metal (in this case ferrous iron, (Fe2+)) using oxygen. This yields solu-bleproducts that can be further

Mineral processing also known as beneficiation aims to physically separate and concentrate the ore mineral(s) using physical, chemical and sometimes microbiological techniques. Metallurgical extraction breaks the crystallographic bonds in the ore mineral in order to recover the desired element or compound [ 2 ].

"With microbes, because we're talking about genomes in their tens of thousands, that's a lot of extra information that could potentially be pulled into a geological model." During recent research work, Reakes came across technical paper on a microbe that can transform gold from its mineral state by consuming it to create a nanoparticle .
