The methods available for cyanide detoxification can be grouped in the following categories Cyanide removal. Natural volatilization. Adsorption onto minerals. Oxidation to the less toxic cyanide species. Natural oxidation. Iron complexation. Hydrogen peroxide process. Sulfur dioxide assisted process.
The Pueblo Viejo plant expansion and mine life extension project is designed to increase throughput to 14 million tonnes per annum allowing the mine to maintain average annual gold production of approximately 800 000 ounces after 2022 (100 basis) and extend the life of mine beyond the 2040s with the incorporation of a new tailings storage
Cyanide destruction plants dose reactants accurately to the tailings stream and can accept control signals from flow monitoring equipment or the plant control system. This ensures that no excess reagents are used and that the cyanide detoxification process is complete. Cyanide destruction can be achieved with several types of reagents. These

The Gidji Roaster is near the town of Kalgoorlie about 600 kilometers east of Perth Western Australia. Tetra Tech Proteus conducted the feasibility study investigation into the type of cyanide destruction method most suitable for the Gidji Roaster operation. Tetra Tech then continued with the detailed engineering design preparation and
Alkaline Chlorination Systems. The predominant mode of cyanide wastewater treatment is alkaline chlorination. This treatment proceeds in two steps. First cyanide is oxidized to cyanate by sodium hypochlorite. This reaction may be brought about through direct addition of sodium hypochlorite or by addition of chlorine gas and sodium hydroxide.
