针对辽宁五龙金矿四道沟分矿的金矿石,研究了影响OCl--I-浸金体系的主要因素。得出了OCl--I-体系浸出的最佳条件是:次氯酸钠的用量占矿浆体积的7%~9%,碘化钾浓度不小于0.25 mol/L,pH值为偏酸性至中性,浸出时间为4 h,在此条件下金浸出率可达85%以上。 According to the gold ore of the Sidaogou sub - grade mine in Wulong gold mine in Liaoning Province, the main factors affecting the OCl - I - leaching gold system were studied. The optimum conditions for the leaching of OCl - I - system are as follows: the dosage of sodium hypochlorite accounts for 7% ~ 9% of the volume of pulp, the concentration of potassium iodide is not less than 0.25 mol / L, the pH value is acidic to neutral, the leaching time is 4 h, in which gold leaching rate of up to 85%.
