摘要
将含１３４ｇ／ＬＭｏ，８９ｇ／ＬＷＯ３，２６１９ｇ／ＬＣＯ２－３的Ｎａ２ＷＯ４原料溶液，用膜电解回收游离碱后，转变钼为硫代钼酸盐，调整溶液浓度，并让其通过三根ｄ２００ｍｍ及一根ｄ３００ｍｍ的串联的交换柱，Ｍｏ、Ｐ、Ａｓ、Ｓｉ在一列交换柱的不同部位被除去，而得到纯（ＮＨ４）２ＷＯ４溶液。
The Na 2WO 4 solution containing Mo 1.34 g/L, WO 3 89 g/L, CO 2 3 26.19 g/L was processed in the expanding test.MoO 2- 4 in aqueous feed was converted into MoS 2- 4 after recovering excess alkali with electromembrane.Thenthe input concentration of feed was regulated, and the feed passed through a series of columns which consist of three d 200 mm and one d 300 mm exchange columns.Mo,P,As,Si were removed in different position of columns. The purified (NH 4) 2WO 4 solution was obtained and the quality of products reached the grade of APT 0(GB10116 88,P R C)
