| Abstract: | An experimental research on leaching efficiency of gold and silver from industrial residues by thiocyanate process has been performed.The results of this study showed that under the conditions of the concentration of ammonium thiocyanate is 6%,the pH value of leaching solution is kept at 1,the dosage of pyrrolusite(MnO2) accounts for 7.5% of industrial residue,the liquid-to-solid ratio is 2,and the leaching time is 5h,the leaching rate of gold and silver can reach 81% and 40%,respectively. |
