中文摘要：

高铁富铟锌焙砂采用传统的热酸浸出工艺,存在锌、铟的回收率低,铁矾渣渣量大等问题。锌还原焙砂热压酸性选择性浸出试验,包括还原焙砂的还原度、酸矿比、热压温度、反应时间等条件试验,综合试验结果得到锌浸出率98.9%、铟浸出率91.4%,铁浸出率6.4%,得到铁渣品位51.75%,铁渣含硫2.13%。

英文摘要：

The high-iron indium-rich zinc calcine is treated by the traditional hot-pressure acid leaching process, which has some problems, such as the recovery rate of zinc and indium is low, high quantity of ammonium jarosite, and so on. The hot - pressure acid selective leaching test of high-iron zinc reduced calcine, including the reduction degree, the acid/ore ratio, hot pressing temperature, the reaction time and the other condition tests of reduced calcine; The comprehensive test results are： the leaching rate of zinc is 98.9%, the leaching rate of indium is 91.4%, the leaching rate of iron is 6.4% , the iron slag grade is 51.75%, the sulfur beating is 2. 13% in iron slag.
