Abstract
The present invention provides a process for the production of aluminum chloride and alumina of metallurgical grade purity, and valuable by-products from aluminous ores like clay, bauxites and laterites. The process comprises carbo-chlorination of the ore to produce aluminum chloride and other metal chlorides. The aluminum chloride is separated, purified and utilized as such or oxidized to make alumina while the other metal chlorides are processed to recover maximum values.
