| Abstract: | For some high arsenic,high carbon,low sulphide,fine grained disseminated gold ore,several different processes of gold extraction process have been carried out.For primary ore with 2.98 g/t gold grade,conventional cyanide method can only obtain 0.68 % leaching rate.Roasting-cyanide process can reach 80 % gold extraction rate.Flotation of primary ore can reach 82.73 % gold recovery.Ore flotation——bio-oxidation of gold concentrate-carbon leaching can obtain a total gold recovery of 74.72 % e;Flotation-hot pressing oxidation of gold concentrate-carbon leaching can obtain 80.98 % gold recovery. |
| Keywords: | fine grained disseminated refractory ore ore roasting biological oxidation high pressure hot oxidation |
