| 摘 要： | 在硫酸体系中用两矿工艺同时浸出含砷金矿和锰银矿,以分解包裹金、银的毒砂和氧化锰矿物.由于毒砂和氧化锰可互为还原剂和氧化剂,因此该工艺降低了贵金属矿的预处理消耗.实验表明,在使用少量水溶性氧化剂NaClO3的条件下,氧化锰、毒砂分解率分别为96%和92%,银、金的浸出率分别可达85.4%和93.5%,总回收率分别为84.5%和93%.

| Abstract: | As-containing gold ore and Mn-containing silver ore were leached simultaneously by sulphuric acid to resolve FeAsS and MnO2. FeAsS and MnO2 can act as reductant and oxidant to each other, and the co-leaching technique reduces the leaching cost. The experiments showed that the resolution rate of MnO2 and FsAsO were 96% and 92% respectively, and the leaching rate of silver and gold were 85.4% and 93.5% respectively, under the condition of using small amount of water-soluble oxidant. The overall recovery rate of gold and silver are 93% and 84.5% respectively. |
