After zinc addition, gold is precipitated from a goldcyanide 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 quot;natural degradationquot;.

In the gold beneficiation process, activated carbon is a vital tool, used to separate gold that has been dissolved in a cyanide solution, so that it can be recovered. The Gold Cyanidation Process. The gold cyanidation process is a series of steps that vary depending on the characteristics of the deposit and the type of mine. Contact Seller

#0183;#32;Destruction of cyanide by microorganisms in gold mill effluents is a natural process that can be readily exploited and engineered to accommodate the large flows and elevated cyanide containing solutions generated at commercial precious metals operations (Akcil and Mudder, 2003).
In gold mining, cyanide has been the preferred lixiviant worldwide since 1887. Although cyanide can be destroyed and recovered by several processes, it is still widely discussed and examined due to its potential toxicity and environmental impact.
The results showed ion exchange to be an effective method of removing iron cyanide to concentrations of less than 3 mg/L. Tests with synthetic gold mill effluents gave resin exchange capacities ranging from 13 to 34 mg CN Fe /mL resin depending on the concentration of

A recently developed process combines sulfur dioxide and air to oxidze cyanide, removing it from industrial waste effluents. The process uses lime for pH control and copper in solution as a catalyst for cyanide oxidation. Significant advantages of the process include thoroughness of cyanide removal, operational simplicity, improved safety and lower reagent requirements.

Destruction of cyanide by microorganisms in gold mill effluents is a natural process that can be readily exploited and engineered to accommodate the large flows and elevated cyanide containing solutions generated at commercial precious metals
#0183;#32;Several methods, such as colorimetric, titrimetric, and electrochemical, have been developed to determine cyanide concentrations in gold mine effluents. Application of physical, natural, biological, and chemical methods to detoxify cyanide to a permissible limit (50 mg L 1 ) can be achieved when the chemical compositions of cyanide (type of species) present in the tailings are known.
