Obtaining Aluminum by the Electrolysis with the Solar Radiation Using1

Abstract

The aluminum production is one of the most energy-intensive processes of modern industry. The paper describes an attempt to obtain aluminum by electrolysis according to the Hall-Herout’s process without utilization of the industrial electric power but due to the cheap renewable environmentally friendly solar energy using. In this version, the electrolysis cell heating is performed by a concentrator of solar radiation while the electrolysis process is carried out with the direct electric current from a solar battery. It is shown that the Hall- Heroult’s process can be carried out by the solar energy exclusively. The proposed approach is a some contri- bution to development of alternative energy industry, in particular in its using in the classical metallurgy pro- cesses.
