摘要
焙砂氰化尾渣、细菌氧化—氰化工艺生产的氰化尾渣 (后简称细菌氧化氰化尾渣 )分别与助浸剂一起细磨 10～ 30min后 ,在选择条件下进行常规氰化浸出 ,可使焙砂氰化尾渣的金品位从1～ 3g/t下降到 0 .3～ 0 .5g/t,细菌氧化氰化尾渣的金品位从 3～ 11.2g/t下降至 0 .5～ 1.1g/t,其中部分氰化尾渣金的氰化浸出率可达 90 %～ 95 %。
After being ground with a leaching aid agent for 10～30 min,a gold grade of a calcine cyanide tailing is reduced from 1～3g/t to 0.3～0.5g/t and the gold grade of 3～11.2g/t for cyanide tailings of biooxidation residues decreases to 0.5～1.1g/t by ordinary cyanidation under selected leach condition. The gold recoveries of some cyanide tailings could come up to 90%～95%.
