The studies on unpolluted deoxidization using solid electrolyte in melt were introduced. It is shown that these studies are control technologies for oxygen ion in different phases. Based on electrochemical characteristics of slag, the feasibility and feature of deoxidization by applying voltage between melt and slag, and the recovery of valuable metal from oxide and slag using SOM (solid oxygen membrane) technique were discussed. In the electrowinning process of MgCl2NdCl3MgO melt, a new technique of producing magnesium metal by SOM was also put forward, in which the MgO is used as the main raw material. It can be shown that the prospects of control technologies for electrified particles in metallurgical process are very bright.
