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％ Arsenic gold and manganese silver ores are simultaneously leached in a sulfuric acid system using a two ore process to decompose arsenopyrite and manganese oxide minerals that enclose gold and silver. Because arsenopyrite and manganese oxide are mutually reducing and oxidizing agents, this process reduces the pretreatment consumption of precious metal ores. Experiments show that under the condition of using a small amount of water-soluble oxidant NaClO3, the decomposition rates of manganese oxide and arsenopyrite are 96% and 92% respectively; the leaching rates of silver and gold reach 85.4% and 93.5% respectively, and the total recovery Rates were 84.5% and 93%
