Abstract

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.

铝土矿粒度分布对物料选矿及改进的影响
在工业上合理利用含铝矿石成分,制造新型功能材料,是选矿与工程的发展趋势之一。化学分析采用x射线荧光法,仪器为Horiba MESA 500。x射线衍射分析采用Shimadsu XRD-6000装置。采用LS 13320 XR激光粒度分析仪(Beckman Coulter)测定其粒度分布。我们比较了x射线相分析和颗粒分析的结果。结果表明,高铁铝土矿和高岭石粘土颗粒深度分选技术在制造功能材料时,提高了原料质量和选矿过程中矿物的利用效率。
