Features of chemical-mineralogical composition and processing properties for medium-ferrous bauxites

Abstract

The features of chemical-mineralogical composition and processing properties of bauxites from Iksinsk and Severoonezhsk deposits are investigated in the paper. It is found that the studied bauxites are coarsely dispersed and low-dispersive, high-Alumina clay raw materials with a high content of colouring oxides. According to their mineralogical composition, Iksinsk and Severoonezhsk bauxites are boehmite-hydrargillite-kaolinite clay bauxites. Moreover, Iksinsk bauxite samples are characterized by the total absence of quartz impurities. The samples of plastic molding based on Iksinsk bauxites are fully sintered at 1500 °C with the formation of strong structures with a compressive strength of 70-120 MPa (depending on the variety of bauxites). The samples based on Severoonezhsk bauxites are fully sintered at 1450 °C, and they are characterized by a compressive strength to 70 MPa in the sintered state.
