Bioremediation of soil and water polluted by cyanide:

Cyanide is a chemical that is widely distributed in the environment, mainly as a result of anthropogenic activities. Only small quantities are naturally produced. Most industrial activities use this chemical compound for manufacturing a product as electroplating or for extracting gold. Exposure to cyanide results in negative health impacts to the wildlife and humans.

Kinetics of natural degradation of cyanide from gold mill

2014-6-18 · After zinc addition, gold is precipitated from a gold-cyanide complex. Waste streams from the process generally contain a sufficiently high concentration of cyanide and heavy metals that treatment is essential. The oldest treatment method practiced by Canadian gold mines for cyanide destruction is "natural degradation".
