近年来 ,在Ａｕ与Ａｇ的浸出中 ,用硫代硫酸盐代替氰化物仍受重视。发现Ｃｕ在浸出中起催化作用 ,而ＮＨ3可使体系稳定。但文献关于氧化剂的报道则存在矛盾 ,尤其对干硫化银 (辉银矿 )。本研究阐述了由物质形态分布计算的浸出化学 ,并对纯辉银矿进行试验。同时 ,确定了氨与硫代 In recent years, in the leaching of Au and Ag, the use of thiosulfate instead of cyanide is still valued. Cu was found to play a catalytic role in leaching, while NH3 stabilizes the system. However, there are contradictions in the literature on oxidants, especially for dry silver sulphide. This study elaborates on the leaching chemistry calculated from the distribution of species and tests on pure galena. At the same time, ammonia and thio were identified
