硫化物氧化时,其所含的细分散的金变成可溶态;金在溶液中最可能的存在形式是硫代硫酸盐络合物。在氧化剂作用下硫代硫酸盐络合物被破后,金即以两种形式——均匀分散状态和独立的微粒沉淀于氧化带矿物颗粒的表面。在清洗氧化带产物时,均匀细分散的金又本能地转入溶液;这种作用在硫代硫酸盐 When the sulfide is oxidized, the finely divided gold it contains becomes soluble; the most likely form of gold in solution is the thiosulfate complex. After the thiosulfate complex is broken down by the oxidant, the gold is precipitated on the surface of the oxidized zone mineral particles in two forms-uniformly dispersed state and independent particles. In cleaning the oxidation zone products, the finely dispersed gold is instinctively transferred into the solution; this action occurs when the thiosulfate
