Research on key metals associated with bauxite in the lower aluminum Benxi Formation of Yuzhou Coalfield
Through the exploration of the three stages of pre-mining,general exploration and detailed investigation of aluminum under coal in Yuzhou Coalfield of Henan province,it was found that key metals such as lithium,gallium and rare earth were widely enriched in bauxite.Through re-sampling and analysis of the strata of the Benxi Formation in the IZK17012 borehole of the Shenzhou Liangbei ore block,the geological characteristics of the alumi-niferous rock series in the Benxi Formation and the key metals enriched therein were studied,and the enrichment characteristics of key metals were sum-marized.The research results show that key metals Li,Ga,W,U,and REE exhibit varying degrees of enrichment,indicating that different types of baux-ite have significant resource potential and economic value.Overall speaking,the resource potential and potential economic value of key metals Li,Ga,W,U and REE in the aluminiferous rock series of the Benxi Formation in Yuzhou Coalfield are enormous.In the future,it is necessary to strengthen the comprehensive utilization of bauxite and improve its comprehensive utilization rate,thus achieving systematic evaluation,development and utilization of as-sociated key metals in bauxite.
