In light of the high cyanide mass concentration of cyanide tailings pulp in a gold concentrate smeltery,experimental research on the comprehensive treatment is carried out.The joint 3R-O,Colt’s and ozone oxidation process is adopted to recover the cyanide and SCN-,and the test conditions are optimized.The results show that the mass concentration of total cyanide decreases to 2.86 mg/L and the removal rate from the cyanide tailings pulp reaches 99.82 %.The mass concentration of SCN-decreases to 2.04 mg/L and the removal rate reaches 99.95 %.The filtrate can be recycled back to cyanidation process;the treated cyanide slag meets the requirement of HJ 943—2018 Technical Specification for Pollution Control of Cyanide Leaching Residue in Gold Industry,realizing stockpiling in tailings pond.The research can provide data reference for the industrial cyanide tailings pulp detoxification application.
