| Abstract: | This article reviews the advantages and disadvantages of the common gravimetric methods for the content determination of tungsten. The conditions of decomposition and precipitation of the 8-hydroxyquinoline gravimetric method to determine WO3 content in tungsten concentrate were studied by stating the best conditions of color reaction. The experimental results show that the sample decomposition is fast and complete, which shows the method is accurate, convenient and efficient. |
