摘要
The subject of the invention is a process for the extraction, from bauxite, from red mud resulting from the processing of bauxite, and from chemically similar materials, °F products of industrial interest, like sodium, iron, gallium, aluminum, titanium and silicon, separated from each other in chloride form. The process involves the melting of the to be treated material and the blowing in the melted bath of chlorine or chlorine in situ generating compounds, and the controlled cooling of the gaseous flow exiting from the melted bath for the selective condensation of chlorides of the elements of interest. The figure shows a block diagram of a particular embodiment wherein the melting is carried out in a transferred arc plasma reactor.
