CFB Alumina Calciners—New and Future Generation Opportunities for Green Field Refineriess. Examples of new developments are described. Further, it is shown how these targets are achieved with new large calciners installed in a new green field alumina refinery. These new features are considering a steady continuous operation. At the same time product quality and energy consumption are improved.

Process Optimization for Diaspore Digestion Equilibrium Using Response Surface Methodology for extraction of alumina from diaspore was identified. The model equation developed using RSM software shows good agreement with the experimental data, with a correlation coefficient (R.) ≥0.96. The characterization of sample before and after digestion was determined by X-ray diffraction (XRD).

Evolutional Development of Alkaline Aluminosilicates Processing Technologyr processing results in more cement produced per tonne of alumina. An economical beneficiation technology has been developed that opens the possibility for more efficient industrial processing of comparatively poor aluminosilicate raw materials in Russia and the rest of the world.

Characterization and Ore Dressing of Bauxite from Brazilnce (XFR) and rheological characterization. CB and MB ore dressing products were characterized by an increase of mass ratio Al.O./SiO. and it was observed that the total silica of MNB, after ore dressing, decreased around 13%. These results were a strong indication that these bauxites could be used in the Bayer process.
