辉钼矿焙烧氨浸得到的钼酸铵溶液含铜、铁杂质,通常用硫化物沉淀法除去,但沉淀物往往夹带一部分钼,硫化物沉淀也待进一步处理。本文简介用N-510(2-羟基-5-仲辛基-二苯甲酮肟)萃取净化钼酸铵溶液,以制取仲钼酸铵和硫酸铜。 (一)有机相的饱和容量 有机相中N-510浓度越高,对铜萃取越有利,但浓度过高,有机相粘 The ammonium molybdate solution obtained from the roasting and ammonia leaching of molybdenum ore contains copper and iron impurities and is usually removed by sulfide precipitation. However, the precipitate often entrains a part of molybdenum and the sulfide precipitation is still to be further processed. This article describes the use of N-510 (2-hydroxy-5-sec-octyl-benzophenone oxime) purification ammonium molybdate solution to obtain ammonium paramolybdate and copper sulfate. (I) Saturation Capacity of Organic Phase The higher the concentration of N-510 in the organic phase, the more favorable the copper extraction is, but the concentration is too high and the organic phase is sticky
