Abstract:The Na2WO4solution containing Mo 1.34g/L, WO389g/L, CO2-326.19 g/L was processed in the expanding test.MoO2-4in aqueous feed was converted into MoS2-4after recovering excess alkali with electromembrane.Then the input concentration of feed was regulated, and the feed passed through a series of columns which consist of three d200 mm and oned300 mm exchange columns.Mo,P,As,Si were removed in different position of columns. The purified (NH4)2WO4solution was obtained and the quality of products reached the grade of APT-0(GB10116-88,P·R·C)
Key words: electromembrane tungsten molybdenum ion exchange
