摘要
内蒙某锌冶炼厂铁矾渣中的主要有价金属为锌和铁,含量分别为3.97%和27.57%,针对该铁矾渣的性质,主要进行了铁矾渣"酸浸-焙烧-酸浸"工艺技术研究。采用该工艺,酸浸渣中的锌含量可降低至约0.085%,锌回收率可达99.11%,酸浸渣铁含量可达到66%以上,作为合格铁精矿产品。该研究成果为国内外锌冶炼厂冶炼废渣处理提供一种新的技术路线,综合回收效果好,具有普遍的社会推广意义。
The main valuable metals in the jarosite residue in a zinc smeltery in Inner Mongolia are zinc and iron, whose contents are 3.97% and 7.57% respectively. Aimed at its properties, the research on acid-leaching-roasting- acid-leaching was carried on. By using this technology, the zinc content in the acid-leaching residue can reduced to 0. 085% ,the zinc recovery could reach 99.11% and the iron content of iron was more than 66% ,which can provide a new comprehensive utilization technology for the treatment of zinc hydrometallurgy stag of zinc smelter at home and abroad. It is meaningful to be widely used for its good recovery.
