摘要
采用等离子光谱、X射线衍射、电子显微分析技术研究了平果铝厂赤泥的化学组成和物相组成.结果表明,平果铝土矿拜耳法处理后的赤泥中含赤铁矿(α-Fe2O3)、针铁矿(α-FeOOH)、水化石榴石(Ca3AlFe(SiO4)(OH)8)、一水硬铝石(Al2O3·H2O)、含水铝硅酸钠(Na2O·Al2O3·1.68SiO2·1.73H2O)、钙钛矿(CaTiO3)、羟钙石(Ca(OH)2)、方解石(CaCO3)等物相,其中赤铁矿和水化石榴石含量较高,赤泥中还含有可供工业提纯价值的Zr,V,Nb,Ta,Sc.
The chemical composition and phase composition of red mud of Pingguo Aluminium Plant have been studied by plasma spectrum, X ray diffraction and electron microscopy. It is shown that: the phase composition of the red mud includs α Fe 20 3, α FeOOH, Ca 3AlFe(SiO 4)(OH) 8, Al 2O 3·H 2O, Na 2O·Al 2O 3·1 68SiO 2·1 73H 2O, CaTiO 3, Ca(OH) 2, CaCO 3. Amony them, α Fe 2O 3 and Ca 3AlFe(SiO 4)(OH) 8 are the main phases. There are Zr, V, Nb, Ta and Sc in the mud as well. Especially, the percentage of Sc is 0 014, which is higher than the refining and exploiting standard of the goverment. The result can be used as a theoretical and trial base for the exploiting of the red mud in the future.
