Abstract

The cyanide is applied in the treatment of gold ores for gold in free solution sterile material product of this treatment is an effluent that must be treated prior to discharge to the sea or rivers. This research aims to develop a methodology for treating the effluent with high free cyanide. The population studied was the effluent from gold cyanidation The results before treatment was 4917 ppm cyanide, is also able to determine the optimum concentration of sodium hypochlorite was 30 to 60 g/l and sodium sulfide was 10 to 16 g/l in a time of 4 to 7 hours after treatment the quantity of cyanide in the effluent decreased from 4917 ppm to the range of 0,0611 to 0,1645 ppm . We have characterized the effluent to design treatment. The conclusion was that the treatment of the effluent cyanide was reduced to smaller quantities of 1 ppm which is within the maximum allowable discharge limits.
