Study on the Recovery of Zinc Minerals from Cyanidation Residue
Based on full investigation of the characteristic of sphalerite in the residue obtained from cyanidation leaching process and the study of the mechanism of the interaction between flotation reagents and sphalerite with the aid of electrochemical analysis,the reagent named YO was developed for eliminating the depression effect of CN- on sphalerite and reducing the dosage of CuSO4.The achievements have been used in commercial production for the treatment of the cyanidation residue to recover the zinc minerals,obtaining a zinc concentrate with grade of 56.49% Zn and recovery of 86.63% Zn.
