association of gold with pyrite in Phu Kham ore was the major reason for gold loss. In mid-2010 the ore feed to the plant changed from mainly supergene secondary copper sulfide mineralisation to mainly hypogene primary mineralisationsulfide, with chalcopyrite typically over 70% of the contained copper sulfide. The change in mineral ...

— The total-oxidation process is particularly advantageous for copper–gold ores. Gold can be recovered by direct cyanidation of the washed autoclave solids. Silver, if present, will likely be fixed at least partly as silver jarosite in the autoclave solids. To improve silver recovery, a lime boil is recommended (2 h at 95°C with an excess of CaO).
— The PLATSOL™ process also offers a noncyanide process treatment option for recovery of copper and gold from copper–gold and gold–copper concentrates. Ferron et al. (2002) reported on batch laboratory testing of a copper–gold concentrate and a refractory gold–silver concentrate under PLATSOL™ conditions.
