难处理含金辉锑矿 (Ｓｂ2 Ｓ3 )在常规氰化过程中 ,锑与氰化钠反应生成稳定的化合物而使氰化物的耗量增加 ,而硫化物晶格中的金因为不能与浸出剂接触难以被浸出。用Ｎａ2 Ｓ和ＮａＯＨ碱性溶液预处理矿石可以破坏硫化物的晶格而使金被释放出来。Ｓ .Ｕｂａｌｄｉｎｉ等人研究了
Difficult to deal with stibnite (Sb2 S3) During conventional cyanidation, antimony reacts with sodium cyanide to form a stable compound that increases the consumption of cyanide, whereas gold in the sulfide lattice can not come into contact with the leaching agent Difficult to be leached. Pretreatment of ores with Na2S and NaOH alkaline solution can destroy the lattice of sulfide and release gold. S. Ubaldini et al. Studied
