Abstract

Brief analysis of the state of affairs in aluminum industry of Russia is presented. A selective chloridation procedure using minerals from the sillimanite group is described as an example. Possibilities for expanding the production of alumina and primary aluminum are suggested based on the chlorine pyrometallurgy processes. The benefits of a technology of this kind over traditional electrolysis in cryolite-alumina melts are: lower electric energy consumption, lower production cost of aluminum, no highly toxic emissions to the atmosphere, and no solid and liquid wastes.
