摘　　要：用硫铁矿与硫酸铟模似高铟高铁闪锌矿的加压酸浸,对影响浸出的始酸浓度、温度、时间、压力等因素进行考察,得出铟会随黄钾铁矾、氢氧化铁胶体、赤铁矿的生成而随铁一起进入渣中,其中赤铁矿晶形较好,铟随其进入渣量最少。为了使浸出过程中铟尽可能少入渣,应减少浸出过程中铁的沉淀,铁的沉淀最好以赤铁矿的形式存在。The marmatite with high indium and iron contents pressure acid leaching process was simulated with py- rite and indium sulfate. The initial acid concentration, temperature, time, pressure and other factors affecting the leaching were investigated. The conclusions drawn are that the indium goes into the slag residues together with the jarosite, iron hydroxide colloid ,and hematite generation ,in which the crystalline hematite is better,indium absorbed by the slag is minimum. In order to make the indium absorbed by the slag as little as possible, the precipitation of iron should be reduced, and the precipitation of iron preferably presents in the form of hematite.
