摘要

The process of the invention is a process for the extraction of bauxite from red mud resulting from the processing of bauxite and from chemically similar materials of products of industrial interest separated from each other. the extraction from bauxite from red mud resulting from the transformation of bauxite processing and from chemically similar materials of products of industrial interest such as sodium, iron, gallium, titanium, aluminum and silicon, separated from each other as chloride. The process involves melting the material to be treated and blowing into the melt bath of chlorine or chlorine generating compound on site, and controlled cooling of the gas stream leaving the melt bath for selective chloride condensation of the elements of interest. Figure shows a block diagram of a particular embodiment wherein the fusion is performed in a transferred plasma arc reactor.
