<p>MAGNESIUM PRODUCTION Docket 6631-G Robert M. Kibby Magnesium metal is produced in a magnesium reduction furnace by the reaction of aluminum metal with a calcium magnesium aluminate slag or with magnesium oxide in the presence of such slag, wherein aluminum is fed to the magnesium reduction furnace as an aluminum silicon alloy and wherein magnesium oxide is fed in less than stoichiometric amounts so that not all of the aluminum is reduced, such additions producing magnesium vapor and two liquid layers: an aluminum silicon alloy having a reduced aluminum content and a MgO?CaO?Al2O3 ? TiO2 slag. The aluminum silicon alloy layer is tapped and recovered from the furnace. The recovered alloy may be used in the production of silicon alloy product by addition to aluminum.</p> |
