An increased gold leach rate of 5 97% can be attained from ore sample minus 30 mm with the K-104 aid. An increment of 10 77% can be obtained from ore sample minus 10 mm by means of leaching with K-104 and then leaching with the L-88 aid.

• 试验表明， －30 mm 矿石采用K－104 助浸， 金液渣平均浸出率可提高5?97 %25 ， －10 mm 矿石采用K－104 预浸及L－88 助浸， 金液渣平均浸出率可提高10?77%25 。
