Study on Separation Manganese Silver Qxidized Qres Process by Amylum Degradation Reduction

摘要：

This paper mainly reported separation manganese silver oxidized ores process by amylum degradation reduction and its influencing factors. When dosage is given according to nMn:nH2SO4:n(C6H10O2)n:nH2O=1:k21.8:k116.66:30,the amount of up to 95.93% Mn leach rate and less than 2% silver loss can be obtained. Cyanidation process was used to extracted silver from leaching Mn residues. Silver leach rate could reach 94.15% at consumed amount of 1kg/t NaCN for 1h. Silver leach recovery rate was more than 92.27% by leaching Mn and cyanidation two-step processes so manganese and silver were separated effectively.
