Separation of Lead from Crude Antimony by Pyro

2016-4-18  In summary, this new pyro-refining process for Pb impurity removal from crude Sb is highly effective, and smoke pollution free, compared with the current processes, which caused by the dehydration of AH 2 PO 4 (A = Na, NH 4) and the reactions between antimony and water vapor. Furthermore, this new process can be combined with the existing industrial equipment of the current
