摘要
含砷难处理金银精矿催化氧化酸浸湿法治金新工艺,采用HNO3作为催化剂、SAA为活化剂、氧气为氧化剂,通过控制温度与压力预处理后进行氰化提金,回收率可由常规的13%~56%提高到92%~95%。
The new catalytic oxidation acid leaching method for refractory gold-silver concentrate containing arsenic used HNO3 as catalyst, SAA as activator and oxygen as oxidant to extract gold by cyanidation through temperature control and pressure pretreatment. The gold recovery could increase from the conventional 13 - 56% to 92% - 95%.
