quantity of residual hydrochloric acid, in consequence resulting in serious environmental problem and a waste of resource. So, there is an increasing need to develop proper leaching system. Compared...), 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......
