Tungsten is a metallic element with the symbol W and atomic number 74, belonging to the VIB family of the sixth cycle in the periodic table. Tungsten is mainly a hexavalent cation in nature, with an iron radius of 0.68 Ã?? 10-10m. Due to the small radius of W6+ions, high electricity price, strong polarization ability, and easy formation of complex anions, tungsten is mainly in the form of complex anions [WO4] 2-, which combine with cations such as Fe2+, Mn2+, Ca2+in the solution to form precipitates of wolframite or scheelite.
