Abstract (en)
[origin: WO2012049696A1] Subject matter of the present invention are a process and a plasma reactor for transformation of red muds, which is a bauxite processing by-product, starting from powdery matrix into a solid, inert and compact residual product, with a remarkably reduced volume, permitting increasing life cycle of dumps using available volumes and from which industrially interesting products can be extracted, e.g. an iron-containing fraction, that can be used in a production cycle of the steel-making sector. A block diagram of the process according to the invention, in one specific embodiment within a transferred arc plasma reactor, is shown in figure 1.
