Laboratory centrifuge to remove impurities from sodium tungstate leaching liquid extraction of tungsten

Removed from alkaline leaching liquid sodium tungstate impurity phosphor, arsenic and silicon is an important working procedure in the process of tungsten hydrometallurgy. Although the process of extraction of tungsten are must in addition to the ability, but the effect is not very good, but due to the formation of heteropoly acid reduces the extraction efficiency of removing impurity of tungsten. So these impurities will be removed in advance before extraction of tungsten, commonly used laboratory centrifuge to remove impurities from the sodium tungstate leaching liquid extraction of tungsten.
traditional subtraction methods mainly include magnesium ammonium complex salt precipitation and so on, the effect is good, but there is also greater loss of tungsten in slag, etc. Extraction method for removing impurity for some research, the use of laboratory centrifuge to remove impurities from the sodium tungstate leaching liquid extraction tungsten has been very good application.
