Bayer Process. Although the low grade diasporic bauxite ore of Yalvaç, Isparta in Turkey is a potential raw material for Bayer Process, ... low grade diasporic bauxite ore and coke was used as raw materials. The chemical composition of the raw materials is given in Table I.
Low-grade diasporic bauxite was treated with hydrocyclone of small cone-angle. The effects of apex diameter, feed pressure and feed concentration on separation indexes were tested, and then the separation process was discussed by hydrokinetics tentatively.
An improved lime-sintering process was developed to produce alumina from low-grade diasporic bauxite in this paper. Both clinkers sintered by the real bauxite and simulated bauxite at 1350 °C when the molar ratio of CaO to Al 2 O 3 decreased to 1.4 were produced, the alumina leaching rates of which reached over 90% in sodium carbonate liquor.
