摘要
采用溶剂萃取法从某复杂低品位铍矿的硫酸浸出液中进行铍的分离,研究了不同因素对铍的单级萃取效果的影响。结果表明,最佳条件为:水相pH=2～2.5、浸出液初始铍浓度1.5～2.5g/L、P204体积分数30%、萃取时间20min、相比为1。在此条件下四级逆流萃取后铍萃取率可达到98.50%。
Beryllium was extracted from the sulphuric acid leaching solution of complex low grade beryllium ore with solvent extraction process.The effecting factors on beryllium single stage extraction rate were researched.The results show that the optimal conditions were pH in aqueous phase of 2-2.5,concentration of beryllium in leaching solution of 1.5-2.5 g/L,volume fraction of P204 of 30%,extraction time of 20 min,and W/O=1.In this conditions,more than 98.50% beryllium is separated by four stage countercurrent extraction.
