Separating Molybdenum in Production Process of Ammonium Paratungstate

Separation of tungsten and molybdenum in production process of ammonium paratungstate is important working procedure ,but this is always one of difficult technical problems .General flows of various ammonium paratungstate technologies and basic nature of molybdenum were summarized .Moreover advantages and disadvantages of each separation method for tungsten and molybdenum in production process of ammonium paratungstate were systemarically analyzed .A nalysis results indicated that there many advantages , such as short process folw small tungsten loss, good molybdenum eliminating effect, simplicity of operation,low environmental pollution and economy feasibility to eliminate molybdenum by ion-exchange method . It is precisely because of these advantages, ion-exchange method to eliminate molybdenum has a good industrial application prospect.
