摘要: article i nfo Keywords: Gold Silver Cyanidation Antimony Refractory ore Alkaline sulphide leaching The pretreatment of an antimonial refractory gold and silver was investigated using alkaline leaching. assayed 20 g/t Au 220 Ag contained predominantly quartz/clay barite, to a lesser extent, sulphides such as pyrite, stibnite, sphalerite, zinkenite (Pb9Sb22S42) andorite (Sb3PbAgS6). latter mineral identified be the most important phase for occurrence silver. Cyanide consistently resulted in low extraction (49%) (18%) confirming nature ore. treatment under suitable conditions shown leach out up 85% Sb, which remarkably improved from b18% 90% subsequent cyanidation step. also enhanced by 20-30%. These findings suggest that Na2S can suitably used method prior conventional Sb-bearing ores.
