The gold grade of the cyanide tailings produced in the bio-oxidation-CIL process by roasting oxidation-cyanide leaching process in a gold mine is relatively high at 2.40-3.60 g/t.The test examines the feasibility of recovering gold from.The results show that when the slag obtained after the tailings are roasted at 500 ℃ under a weak oxidizing atmosphere for 120 min is subjected to cyanidation with CaO dosage 15 kg/t,slurry concentration 33 %,NaCN dosage 1.0 kg/t and leaching time 24 h,the yield of leaching slag is 88.80 % and leaching rate of gold is over 94.92 %,which proves that it is feasible to recover gold in the cyanide tailings by the roasting oxidation-cyanide leaching process.The study provides data reference for the gold recovery from cyanide tailings.
