河南省嵩箕地区铝土矿Li、Ti、Zr、Ga、Nb和LREE的矿化分析

Mineralization of Li,Ti,Zr,Ga,Nb and LREE of bauxite deposits in Songji area of Henan

通过对河南省嵩箕地区大峪沟、涌泉、朝阳沟、青石沟、孙桥、白坪等6处铝土矿床进行了稀有金属、稀土、稀散元素成矿潜力初步研究。19件铝土矿及铝质粘土岩样品的分析结果揭示了Li、Ti、Zr、Ga、Nb和LREE的矿化信息,为河南省嵩箕地区铝土矿中"三稀"矿产资源的勘查提供有益的参考。嵩箕地区铝土矿的Al_2O_3含量与TiO_2、Zr和Nb含量呈正相关关系,这可用于初步评价铝土矿中的Ti、Zr及Nb是否达到矿化。

This paper conducted a preliminary study on the mineralization potential of rare metals,rare earth elements and dispersed elements of 6 bauxite deposits in Dayugou,Yongquan,Chaoyanggou,Qingshigou, Sunqiao and Baiping in Songji area of Henan.The analysis results of 1 9 samples from bauxite and aluminous clay rock provide the mineralization information of Li,Ti,Zr,Ga,Nb and LREE which give reference for prospection of the three mineral resources (rare metals,rare earth elements and dispersed elements)of bauxite deposits in Songji area of Henan.There is a positive correlation between Al2 O 3 content and the contents of TiO 2 ,Zr and Nb of bauxite deposits in Songji area.It can be used in the preliminary assessment of the mineralization status of Ti,Zr and Nb of bauxite deposits.
