摘要: 针对某金矿金载体矿物分散,金嵌布粒度微细,采用常规捕收剂金回收率不高的问题,采用新型MAC-12捕收剂对该金矿石进行强化浮选试验研究。结果表明, MAC-12是一种金高效捕收剂,在pH=9左右的弱碱性条件下,金的回收率比丁胺黑药提高5.41个百分点,金品位提高18.74 g/t,MAC-12的使用改善了金的浮选指标。

Abstract: In view of the discrete gold ore,and low gold recovery for some fine or extra-fine gold ores by the conventional collector,Mac-12 collector was used to improve gold recovery.The experimental results showed that Mac-12 is a high effective collector for gold.Under the condition of low alkaline medium at pH 9,and compared with the butylxanthate,the flotation index with gold recovery can be improved by 5.41%,and gold grade by 18.74 g/t by Mac-12 collector.
