How to Recover Tungsten and Ammonium Chloride from APT Mother Liquor?

How to recover tungsten and ammonium chloride from APT mother liquor? The researchers proposed a new type of recycling method of ammonium paratungstate mother liquor. The method is simple to operate, consumes a smaller amount of chemical reagents, has lower operating costs, and has a higher recovery rate of tungsten than traditional methods. In addition, the separated ammonium chloride solution can be new_ed to or used for other purposes after proper purification.

A Method for Recovering Tungsten and Ammonium Chloride from APT Mother Liquor
The nanofiltration or ultrafiltration membrane separation process is used to separate the tungsten and chloride ions in the ammonium paratungstate crystal mother liquor, and the tungsten-containing solution is directly new_ed to the main process of ammonium paratungstate by the ion exchange process.
