Highlights

Environmental-friendly reagent Jinchan was used as a substitute for sodium cyanide to treat Xiajiadian gold mine,and the leaching effect of Jinchan and sodium cyanide was compared.The results showed that the leaching rate of Jinchan and sodium cyanide was 88.55% and 88.73% respectively,which was basically the same when the dosage of reagents was 200 g/t；When Jinchan dosage was 300 g/t，the leaching rate of 89.87% could be obtained，which was obviously better than the leaching effect of sodium cyanide under the optimal conditions；When using Jinchan，the adsorption and desorption effects were the same as that of sodium cyanide,with gold desorption rate of 98.99% and 98.97%, respectively；Jinchan as a substitute for sodium cyanide，could significantly improve technical and economic indicators，and moreover，in view of the non-toxicity of Jinchan，the invisible benefits of transportation，management，environmental protection and safety also would be obtained.
