ABSTRACT:
Aluminum chloride is produced from clay containing aluminum oxide and silicon oxide by chlorinating the clay through contact with a mixture consisting essentially of a chlorinating agent, a reducing agent, an alkali metal compound catalyst, and silicon chloride; and thereafter separating the reaction products from the chlorination step; and recycling back to the chlorination step substantially all the silicon chloride separated from the reaction products to thereby promote the chlorination of the aluminum oxide in the clay while suppressing chlorination of the silicon oxide.
