A method for separating and extracting industrially important products from bauxite, from red mud resulting from the processing of bauxite and from chemically similar substances

摘要

The subject of the invention is industrially important products such as sodium, iron, gallium, aluminum, titanium and silicon from bauxite, from red mud resulting from the processing of bauxite and from chemically similar materials. Are extracted from each other in the form of chloride. This method melts the material to be treated, blows chlorine or a compound that generates chlorine in situ into the melting tank, and controls and cools the gas flow discharged from the melting tank, thereby Including performing selective condensation. The figure shows a block diagram of a particular embodiment in which melting occurs in a transfer arc plasma reactor.
