Tungsten smelting Theory and Applications describes a new method of tungsten smelting and theoretical studies of the leaching process. given the leaching process intensification theory; deep purification and separation for solution similar elements discussed directionally looking for effects reagent ideas to achieve efficient separation; ion exchange for tungsten. discussed enhanced ion exchange reaction unit operation and the process of direct adsorption of the high concentration of tungsten. Tungsten smelting Theory and Applications is available in the precious metals. especially tungsten smelting of scientific and technical personnel. university teachers and students of metallurgy read reference.
