铝土矿是生产氧化铝的主要原料,除氧化铝外,还含镓、钒、钛、氟、磷、钼、锆、钪等杂质元素。但直到不久以前,在加工铝土矿时只能回收氧化铝。目前,在巴甫洛达尔炼铝厂,从铝土矿矿石中还能获得镓和钒,而在其它炼铝厂则只能单独获得镓或钒。哈萨克斯坦科学院冶金和选矿研究所与巴甫洛达尔炼铝厂一起编制了按巴耶尔流程(烧结法)生产氧化铝时铝土矿中有价组份元素在产品、中间产品和尾矿中的分布平衡表。已确认,巴耶尔分支流程的母液和循环液是获取镓、钒和磷的最适宜的来源。应当指
Bauxite is the main raw material for the production of alumina, in addition to alumina, but also containing gallium, vanadium, titanium, fluorine, phosphorus, molybdenum, zirconium, scandium and other impurity elements. Until recently, however, alumina was only recovered during the processing of bauxite. Currently, gallon and vanadium are also available from bauxite ore at the Pavlodar smelter, while in other smelters only gallium or vanadium are available separately. The Institute of Metallurgy and Mineral Processing of Kazakhstan Academy of Sciences and Pavlodar Aluminum smelter have prepared the production of alumina by the Bayer process (sintering method) when the valuable components of bauxite in products, intermediates and tailings The distribution of balance sheet. It has been confirmed that the mother liquor and recycle solution of the Bayer branch process are the most suitable sources for obtaining gallium, vanadium and phosphorus. Should mean
