(PDF) The Use of Oxygen in Gold Cyanidation Wesley

Optimum gold dissolution rate as a function of dissolved oxygen cyanide levels in the gold plants is the suggested approach for and “free” cyanide concentration (constants : pH = 12.0, high gold

The use of oxygen in gold cyanidation ScienceDirect

Gold leaching optimization studies were performed with one gold ore sample. Cyanide consumption was found to be strongly affected by the leaching pH and the “free” cyanide concentration in the slurry. High dissolved oxygen concentration as well as high lead nitrate addition, pH and “free” cyanide concentration favour fast gold

The effects of dissolved oxygen and cyanide dosage on gold

Feb 01, 2004 Fig. 1 illustrates the leaching and adsorption circuit schematically, outlining the cyanide and oxygen addition points. The residence time in tanks 1and 2 is 4.5 h at the rate of 115 tph and 50% solids w/w and for other tanks 3.5 h. The last six tanks in Fig. 1 are the gold cyanide adsorption stages. The activated carbon is regenerated in a

Effect of Oxygen on Gold Leaching

Dec 25, 2015 Effect of Oxygen on Gold Leaching. In simplified terms, the Effect of Oxygen on Gold Leaching can be summarized in saying: The dissolution rate of gold in alkaline cyanide solutions under atmospheric conditions, and at practical cyanide levels, is directly proportional to the dissolved oxygen concentration. The rate of dissolution of gold
