| 摘 要： | 对高氟氯含量的次氧化锌粉,先通过碱洗工艺去除原料中的大部分氟氯,氟的脱除率50.21%,氯的脱除率92.98%。得到的碱洗次氧化锌粉采用两段硫酸浸出回收其中有价金属锌铟,得到锌浸出率为92.7%,铟浸出率为75.8%。通过对浸出液进行沉铟试验,得到的沉铟渣铟品位为6775g/t,沉铟工序铟回收率为98.5%。试验效果理想,工艺可行。

| Abstract: | With regard to high fluoride and chlorine content of second-rate zinc oxide powder, first remove most fluoride and chlorine of raw material by caustic wash process, the removal rate of fluoride and chlorine reaches 50.21% and 92.98%. Then, adopt two-stage sulfuric acid leaching to recovers zinc and indium from second-rate zinc oxide powder which was washed by soda, the leaching rate of zinc and indium were 92.7% and 75.8%. When neutralization for precipitating indium to single-stage leachate, got the indium residue grade was 6775g/t, indium recovery rate was 98.5%. The experimental result was satisfactory, and technology was feasible. |
