为了从高含硅、含铁等的氧化锌矿中提取锌 ,设计了低酸浸出、针铁矿除铁并脱硅提锌的新工艺。经探索实验和周期实验结果表明 :锌浸出率为 95 .5 6% ,铁、二氧化硅的入渣率分别为 96.91%、95 .95 % ,流程畅通 ,运行稳定 ,达到了有效回收锌和脱除杂质的目的 ,可为类似氧化锌矿提锌建厂提供参考。 In order to extract zinc from high-silicon and iron-containing zinc oxide ore, a new technology of low acid leaching, iron removal from goethite and zinc removal from silicon was designed. The results of the exploration experiment and periodic experiment show that the leaching rate of zinc is 95.56%, the feeding rates of iron and silica are 96.91% and 95.95% respectively, the flow is smooth and the operation is stable, and the effective recovery of zinc and Removal of impurities for the purpose of similar Zinc oxide mining zinc plant to provide reference.
