After the close contact of microbes with the mineral ore, sulfide mineral ore gets oxidized by hypothesizing the electrons transferred from the microbial surface during respiration [47] or enzymatic oxidation reactions [48] and solubilizes the mineral ore surface. Still, this mechanism of metal oxidation is in its infancy.
