| 中文摘要: |
| 滇东南地区铝土矿资源丰富。文章以滇东南主要铝土矿床为研究对象,对其中共生、伴生的矿产进行了评价。全区含铝岩系w(TiO2)平均值为4.58%,明显高于钛原生矿床的边界品位,并且有92.6%的样品分析结果已超过钛原生矿床的边界品位;w(ΣREE)平均值为769.10×10-6,接近吸附性稀土矿床的边界品位,其中有45.7%的样品分析结果超过吸附性稀土矿床的边界品位;w(Nb)平均值为121.03×10-6,为风化壳型铌矿床的边界品位的2倍多,并且有84.0%的样品分析结果高于风化壳型铌矿床的边界品位;w(Ga)平均值为28.86×10-6,高于铝土矿之中镓的最低工业品位,其中有68.5%样品的分析结果超过了铝土矿之中镓的最低工业品位。滇东南地区铝土矿床稀土元素、黑色金属元素钛和稀有金属元素铌含量高达边界品位,可考虑综合利用。 |

| The southeastern Yunnan province is abundant with bauxite resources. This paper researches on the major bauxite deposits and is concentrated on evaluation of the by-products. Average content of TiO2 of 92.6% of total samples from the aluminum-bearing rock in the deposits is 4.58%, much higher than the cut-off grade of Titanium of the primary aluminum deposits; average content of ΣREE of 45.7% of total samples 769.10×10-6,approximate to the cut-off grade of the adsorption rare earth deposits; average content of Nb of 84.0% of total samples, 121.03×10-6,about two times of the cut-off grade of the lateritic Nb deposit; average content of Ga of 68.5% of total samples 28.86×10-6,higher than minimum content of bauxite ore. Comprehensive utilization of the by-products should be considered. |
