摘要: 运用湿化学法对栾川钼尾矿中有价金属元素进行回收利用,实现了铁、钙、镁的提取和分离。通过改变试验条件对目标元素进行提取分离,获得的关键工艺参数为:钼尾矿与浓度为20%的盐酸溶液固液比1∶6,95 ℃水溶液中酸浸6 h。采用该法获得的铁、钙、镁的提取率分别达到86.15%,83.29%和80.24%,其中铁、钙、镁产品的纯度分别为98.27%,97.97%和83.07%。通过提取钼尾矿中含量较高的铁、钙、镁,可以实现主元素钼以及含量较少的铜、钨等金属元素的富集,为后续的提取节约除杂成本。

Abstract:  Extracted and separated valuable metals,like Fe,Ca and Mg,from molybdenum tailing in Luanchuan by Hydrometallurgy method.The results showed that the leaching ratios of Fe,Ca and Mg could reach 86.15%,83.29% and 80.24%,respectively,when the tailings were leached in 20% hydrochloride acid for 6 h under the water temperature at 95  ℃.Also,the purity of the related compounds containing Fe,Ca and Mg were up to 98.27%,97.97% and 83.07%,respectively.After the aid leaching mentioned above,other valuable elements,such as Mo,Cu and W,were naturally enriched.It would save the cost in the later extracting process.
