Tungsten Concentrate AMERICAN ELEMENTS

Tungsten concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas.

2019-10-1  Tungsten, as a strategical rare metal, is one of these critical raw materials. It is an essential component in a wide range of products for many end uses (Lassner and Schubert, 1999, Trasorras et al., 2016, BGS, 2011a, Gunn, 2014).Particularly, the use of tungsten in hard metals represents its most important application.

Ion exchange hydrometallurgy of tungsten using anion

1999-8-1  The resin saturation with tungsten ions depends on initial tungsten concentration in solution. Thus, the tungstate ions (WO 4 2−) exist mainly in initial solutions at tungsten concentration less than 10 −3 M. With the increase of tungsten concentration, the formation of polyanions W 7 O 24 6−, [H 2 W 12 O 42] 10−, [H 2 W 12 O 40] 6− takes place. Therefore, the anion exchangers are
