cyanide (TCN) below mg/L may be required; however, control of spigot discharge to TSF is by far the main application of cyanide destruction in the gold industry. The main routes for cyanide removal from gold plant tailings and effluents include the oxidation of cyanide by means of sodium metabisulfite (SMBS, or SO 2) with air, Caro‟s ...
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 general, the primary concern with cyanide effluent is its propensity to form complexes which are difficult to remove and can later break down to highly toxic forms. During the course of this study, a new approach to the destruction of cyanide and cyanide complexes was developed.
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.

Abstract. The intermediate and terminal products of cyanide and thiocyanate decomposition by individual strains of the genus Pseudomonas, P. putida strain 21 and P. stutzeri strain 18, and by their association were analyzed. The activity of the enzymes of nitrogen and sulfur metabolism in these strains was compared with that of the collection strains P. putida VKM B2187 T and P. stutzeri VKM ...

Key words: Cyanide destruction, hydrogen peroxide, copper sulfate, optimum pH, cyanide INTRODUCTION Cyanides are present in effluent waters of several industries especially in chemical and mineral processing industry. Mineral processing industries, especially gold processors, use a great deal of cyanide Ingles and Scott, 1993. Cyanide is used in
Cyanide (CN) is a toxic species that is found predominantly in industrial effluents generated by metallurgical operations. Cyanide''s strong affinity for metals makes it favorable as an agent for metal finishing and treatment and as a lixivant for metal leaching, particularly gold. These technologies are environmentally sound but require
hardening of steel, and refining of gold and silver ores. Wastewater from these processes that contains even trace amounts of cyanide must be treated before discharge into sewage systems. Cyanide wastewater treatment is critical, because cyanide wastes are toxic to living organisms. Specifically, cyanide may reduce
Cyanide Destruction Mining SGS. The destruction of cyanide in gold tailings is a crucial part of metallurgical recovery of gold. Many jurisdictions have strict regulations controlling the destruction of cyanide and metal cyanide in tailings prior to discharge into the environment.
