    Abstract. 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. Biological treatment of cyanide is a well-established process and has been commercially ...

  • Kinetics of natural degradation of cyanide from gold mill ...

    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".

  • Destruction of cyanide and thiocyanate by ferrate [Iron(VI)]

    cost effectiveness are needed to treat cyanide and thiocyanate in wastewater. We herein propose a novel oxidant, ferrate [Iron(VI)] for destruction of cyanide and thiocyanate in gold mill wastewaters. 2. FERRATE (IRON(VI)) Iron is commonly exists in the +2 and +3 oxidation states; however, in a strong oxidizing environment,

    11-10-2019 · 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

  • Cyanide and removal options from effluents in gold mining ...

    Cyanide in effluents resulting from gold mining is known to be the prime candidate for treatment. However, according to a study by the Ontario Ministry of the Environment (Canada); ammonia, suspended solids and copper were identified as the most important contaminants in gold mining effluents rather than cyanide.

    Cyanide has been in use in the extraction of gold for the last 100 years, and so cyanide containing effluents have had to be disposed of in some way for this period of time. With the current expansion of the gold mining industry and the generally increased environmental awareness, cyanide detoxification is now becoming of paramount concern to mine operators.
