Gold Extraction

Gold Extraction

Jeffrey et al. (2008a,b) observed that increasing the pH value from 8.5 to 10.5 increased the gold leaching efficiency from 7% to 70% from a pressure-leach residue of a refractory gold ore after 1 h in 50 mmol/L (NH 4) 2 S 2 O 3 and 0.5–2 mmol/L CuSO 4. However, leaching of gold after 24 h at pH 8.5 was similar to that observed at higher pH ...
