Bioleaching (or biomining) is a method in mining and bio hydrometallurgy (natural processes of interactions between microbes and minerals) that extracts valuable metals from an inferior ore with the assistance of microorganisms like bacterium or archaea. These techniques are usually more practical than ancient mining applications and may even be accustomed to clean mine tailings sites. Metals extracted from bioleaching include: Gold, Copper, Silver, Cobalt, Uranium, Zinc, and Nickel Some methods of bioleaching include Direct & Indirect Bioleaching: Direct bioleaching uses minerals that are simply receptive to oxidization to make an immediate accelerator strike exploitation the microorganisms to separate the metal and therefore the ore. In indirect bioleaching, microorganisms aren't in direct contact with minerals throughout the method. However, action agents are created by microbes that still oxidise the ore.
