Case study flowsheets: copper–gold concentrate treatment ...

Jan 01, 2005  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).

Process for treating refractory gold ores by roasting ...

Microscopic gold inclusions in sulfide minerals cannot typically be extracted by conventional cyanidation. The gold ore must be pretreated to oxidize sulfide minerals associated with gold and to remove other minerals and chemical compounds that interfere in the cyanidation leaching process. The recovery of gold from refractory sulfidic-carbonaceous ores after roasting pretreatment was studied.
