  • Beneficiation of Aluminum Iron and Titanium Bearing

    Beneficiation of Aluminum Iron and Titanium Bearing

    Dec 12, 2016 In this study, extraction of aluminum-, iron-, and titanium-bearing constituents from diaspore-type bauxite ores was investigated by stepwise treatment consisting of pre-desilication via alkali-leaching of bauxite ore, extraction of alumina via Bayer process, and recovery of iron from red mud via magnetic separation. The pre-desilication results showed that the removal of silica reached … read more

    Jul 01, 2001 Fine concentrate with a grade of 48% [Cr.sub.2][O.sub.3] was obtained in a 24% mass for a 70% [Cr.sub.2][O.sub.3] recovery (on the basis of total minus 100 micron tails). On this basis, an MGS fines recovery unit retrofitted in the spiral section of the concentrator could increase the plant concentrate yield by up to 11%. read more

  • Beneficiation of bauxite

    Beneficiation of bauxite

    from the process along with the insoluble iron and titanium oxides in red mud, consequently entailing the loss of valuable alumina and caustic soda from the process. The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. read more

    Bauxite Beneficiation An Approach to Value Addition in

    Jul 02, 2021 The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals. read more

  • A process for enhanced removal of iron from bauxite ores

    A process for enhanced removal of iron from bauxite ores

    Jun 01, 1991 A process for enhanced removal of iron from bauxite ores. Int. J. Miner. Process., 31: 233-246. A process to remove iron from bauxite ore is described in which the ore is first finely crushed, calcined, and contacted with a reducing gas to convert iron present as very weakly magnetic goethite or hematite to magnetite or elemental iron. read more
