Biodegradation of cyanidecontaining wastes by .

In the mining of precious metals, cyanide is widely used to leach gold and silver from the ore. The cyanidation process converts gold and silver to water soluble cyanide complexes [7]. Each year over a billion tons of gold ore are treated using this process, which means a significant demand for cyanide by these industries. [8].
