Ion exchange technology has played an important role in the process of the purification and transformation of tungsten metallurgy, especially since the development of strong basic anion exchange technology. A brief review on the developments of the technology is given associating with the resin modification, exchange mechanism and reaction engineering, especially comparing the ion exchange technology of highly concentrate tungsten solution with the past one. In addition, the existing problems are discussed. The development of highly efficient resin, new exchange technology or advancing the ion exchange technology theory to improve resin's tungstate selectivity and the higher content of hazard solid salt in waste water are some suggested solutions.
