Gold Extraction - an overview ScienceDirect Topics

The increase in gold extraction can be attributed to increases in residual Cu(II) in solution with increasing pH value resulting from the increase in free NH 3 (Senanayake, 2004a,b). Leaching at a higher pH value can also be beneficial in improving silver extraction and stabilizing silver in solution. In addition, operating at a higher pH value favors the hydrolysis of the thiosulfate ...
