供给巴夫洛达尔铝厂生产氧化铝的哈萨克斯坦铝土矿是由致密的、疏松的和高岭土类物质组成的,属于三水铝石型、高岭石—三水铝石型和三水铝石—高岭石型矿石,并含有碳酸盐,高岭石,黄铁矿,磁铁矿,针铁矿,硅化木碎屑。致密的和疏松的铝土矿的主要矿物是三水铝石,伦琴结构分析发现有少量的勃母石。高岭石是铝土矿中氧化硅的主要载体矿物,其中有70——75%的二氧化硅赋存于高岭石中。在致密的矿石类型中,二氧化硅的含量较少,但在疏松铝土矿和粘土质铝土矿中发现有大量的二氧化硅,而在高岭石中,这种造岩
Kazakhstan bauxite supplied to produce alumina from Pavlodar Aluminum Works is composed of dense, loose and kaolin-type materials belonging to the gibbsite, kaolinite-gibbsite type and trihydrate Stone - kaolinite type ore, and contains carbonate, kaolinite, pyrite, magnetite, goethite, siliconized wood debris. The main mineral of dense and loose bauxite is gibbsite, Roentgen structural analysis found a small amount of boehmite. Kaolinite is the main carrier of silicon oxide in bauxite, of which 70-75% of silica is present in kaolinite. In dense ore types, the silica content is low, but a large amount of silica is found in loose bauxite and clayey bauxite, whereas in kaolinite, this type of rock formation
