发明名称 METHOD OF RECOVERING MAGNESIUM FROM MAGNESIUM ALLOY WASTE
摘要 <p>A process for recovery of magnesium from magnesium alloy waste by charging an electric furnace with a flux including at least one salt, the flux being inert with respect to magnesium and having a melting point <1000 DEG C. The flux is raised by the Joule effect at a reduced pressure to a temperature of 900 DEG to 1100 DEG C. to produce a bath having a density higher than that of magnesium, a vapor pressure <0.1 torr and an electrical resistivity of between 1 and 10 milliohm.m. The magnesium alloy waste is introduced in the bath, and magnesium and any other elements in the waste which are more volatile than magnesium are recovered from a vapor phase above the bath. Any elements in the waste which are less volatile than magnesium are recovered from a molten phase in a bottom portion of the furnace.</p>
