Influence of Mineral Composition on Properties and Integrated Processing Prospects of Ferruginous Bauxite

Abstract

The article describes the tests of thermal treatment effects on magnetic properties of bauxites and the results of their dry magnetic separation. Under increasing temperature in a muffle furnace to 600 °C, the magnetic susceptibility of treated bauxites decreases. The thermal radiation modification of bauxite by accelerated electrons under the same temperature improves the magnetic properties of the mineral. Magnetic separation efficiency is governed by the thermal treatment conditions. The process parameters to ensure extraction of rare and rare earth elements to the magnetic fraction are found.
