摘　　要：介绍了几种化学药剂对某铁帽型金矿氧化矿石柱浸提金效果的影响。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 ％ ， －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％ 。Effects of chemicals on gold extraction with column leaching from oxidized ores of an iron-cap type deposit are investigated.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.
