Concentrating Table For Impurity Removal Small Scale

Process Methodology For The Small Scale Production Of

Jul 01, 2010 Almost for all impurities the removal efficiency was 99 except for Mg and Ag. The decrease of the Mg removal efficiency can be related to the low input concentration in the starting material as well as with the high p v with respect to all other impurity elements. In the case of Ag after the 1st distillation, the separation efficiency ...
