Bioleaching Wikipedia

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several appliions within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

However a study by MujeeburRehman shows that 75 percent of the copper in the ore studied was leached in 144 hours. Leaching can be carried out in two stages that permit separate enhancement during each stage. The biological oxidation stage is fast and effective.
