Oxygen uptake test on gold leaching
WebAug 1, 1993 · Oxygen uptake rates were measured for each injection method. It was found that the oxygen dissolution efficiencies were approximately 26% and 4.4% for the Filblast unit and the bubbler, respectively. Slurry samples from three gold mines were used for the remaining tests. WebOxygen is one of the reagents consumed during cyanidation, accepting the electrons from the gold, and a deficiency in dissolved oxygen slows leaching rate. Air or pure oxygen gas …
