摘　　要：在以银阳极泥为原料 ,提取其中的金、铂、钯等金属过程中 ,研究了用氯酸钠取代氯气浸金时 ,氯酸钠用量、酸度、反应时间和稳定剂用量等因素对浸金效率的影响 .结果表明 ,该工艺氯化剂利用率高、反应速度快 ,并减轻了环境污染 .Effects of sodium chlorate addition, acidity, reaction time and guantity of stabilizer on leaching recovery of gold are studied when chlorine was replaced by sodium chlorate in the process of recovering Au, Pt, Pd from silver positive electrode mud. The results show that the process has the advantages of higher utilization ratio of sodium chlorate, faster reaction speed and less environment pollution.
