| Abstract: | The experimental reseach of gold leaching of hot-press acid leaching residues by amm-moniacal cyanide process and the effects of various operation condition on gold extraction have been investigated in this paper. The extraction of Au ,Ag is 98.3% ,82.7% respectively under conditions that granularity of concentration of mine slurry is 20%, the NaCN and NH4HCO3 is 8kg/t and 75kg/t respectively,and ammoniacal cyanide treatment time as lone as 16h. |
