本文论述了黔中铝土矿和其紧密伴生硬质粘土岩及其炼铝残渣赤泥中的钪和稀土元素含量与分布特征，通过淋滤实验、酸处理实验、人工合成方钠石及电子探针分析等手段，探讨了钪在赤泥中的赋存特征。
In this paper, the contents and distribution characteristics of scandium and rare earth elements in the bauxite and its closely associated hardclay rocks in Guizhou Province and their red mud of the aluminum-making residues are discussed. The leaching experiments, acid treatment experiments, synthetic sodalites and electrons Probe analysis and other means to explore the occurrence of scandium in the red mud characteristics.
