ABSTRACT:
A method of producing magnesium vapor at substantially atmospheric pressure. The method comprises feeding into the reaction zone of a reduction furnace magnesium-oxide containing materials and metal reductants and then heating the magnesium-oxide containing materials and the metal reductants in the reaction zone to an operating temperature to create a slag composition. The slag composition has a phase diagram including a two-phase liquid and solid region. The feeding of the magnesium-oxide containing material and the metal reductant into the furnace bath are controlled such that the slag composition at the operating temperature is within the two-phase liquid and solid region of the phase diagram. In this way, reactions occur to produce magnesium vapor at substantially atmospheric pressure. A method of producing magnesium metal is also disclosed.
