Abstract
The present invention is concerned with a system for the filtration of molten material. The system is particularly useful for removing MgO impurities present in molten magnesium chloride electrolyte. The invention also comprises a method for removing solid particles from molten materials. Preferred molten materials include magnesium, aluminum, magnesium chloride electrolyte and aluminum electrolyte. The concentration of solid remaining in the molten material is less than 0.05 wt %.
