| 摘 要： | 利用电子探针背散射电子成像分析和微区成分分析功能,对贵州瓮福高镁磷尾矿的矿石结构和矿物组成进行了研究,以探索尾矿与其原矿之间的差异,为综合开发利用磷尾矿提供必要的依据。结果表明该高磷尾矿的矿石结构可分为单矿物结构和多矿物碎屑结构两类。前者矿物组成包括白云石单矿物、磷灰石单矿物、褐铁矿单矿物、石英单矿物;后者包括白云石-磷灰石多矿物、磷灰石-白云石-石英多矿物,属高镁低品位磷矿。矿物组成类型按其含量从高到低依次为白云石质尾矿、白云石磷灰石质尾矿、磷灰石白云石石英质尾矿、石英质尾矿、磷灰石质尾矿、褐铁矿质尾矿,白云石质尾矿是尾矿中最丰富的矿物,白云石颗粒是含量最高的碎屑类型。 |
| 关 键 词： | 高镁磷尾矿 综合利用 矿石结构 矿物组成 |

| Abstract: | The ore structures and mineral composition of phosphate tailing with high magnesium content from Wengfu phosphate rock in Guizhou Province,China were researched by using back scattered electrons images and probe analytical spectrogram so as to reveal the differences between tailing and its originals,which could provide the necessary basis for tailing's comprehensive recovery.The results showed that the tailing had several kinds of internal structure styles including monosize and polysize particles in genera... |
