Effect of Bauxite Grain Size Distribution on Beneficiation and Improvement of Materials

The rational use of the constituent aluminum-containing ores in the industry to create new functional materials is one of the promising trends of mineral processing and engineering. Chemical analysis was carried out by X-ray fluorescence method using Horiba MESA 500. Shimadsu XRD-6000 device was used for X-ray diffraction analysis. The particle size distribution was determined by LS 13 320 XR laser particle size analyzer (Beckman Coulter). We compared results of X-ray phase and granulometric analyses. It was shown that the technology of deep fractionation of particles of high-iron bauxites and kaolinite clays improved the quality of raw materials and efficiency of use of minerals in enrichment processes and various industries, when creating functional materials.
