According to the cyanide residue tailings pond disposal requirement by HJ 943—2018 Technical Specification for Pollution Control of Cyanide Leaching Residue in Gold Industry and its own conditions,Jilong mining company employs modified solid-liquid separation washing process to upgrade cyanidation process flowsheet,and integrates press filtering-washing-blowing elution-leach solution treatment 4 processes after adjusting and optimizing their parameters,forming "2 washing,3 blowing,1 purification" treatment process,which reaches the minimum limit of the regulated cyanide residue tailings pond disposal requirement,guarantees the water balance of the whole production flowsheet and effectively recovers valuable materials from cyanide tailings.
