Abstract
A process for the production of aluminum chloride from raw materials such as coal slate or bituminous shale is disclosed. The raw material should preferably have an ash content of at least 30% by weight, and with the aluminum content of the ash being at least 20%, calculated as Al.sub.2 O.sub.3. The raw material is first calcined and then chlorinated with a gaseous stream containing chlorine and carbon monoxide to form the aluminum chloride product.
