a hydrometallurgical process to extract tungsten from scheelite ores. In the process, the scheelite concentrate was decomposed with nitric acid and phosphoric acid to produce a phosphotungstic acid...), both products (phosphotungstic acid and Ca(NO3)2) are soluble, which fundamentally avoid the tungstic acid precipitation and wrapping. In contrast to the classic leaching by hydrochloric acid......
