Bacterial oxidation of refractory gold concentrates

For downstream processing, the pH value of the oxidized residue is adjusted with lime prior to gold leaching with cyanide. Often the addition of antifoam is required to reduce foam formation during cyanidation. Both the carbon in leach (CIL) and Merrill Crowe processes have been used successfully for gold recovery from bacterial oxidation residues.
