In most cases, the microbes break down these minerals by oxidising the sulfur and iron within them. Because metals such as copper, nickel and zinc naturally form sulfides, while other metals such as gold are trapped, or occluded, within sulfide and ironcontaining minerals, this oxidation process ends up releasing the metals.
