Study on the Geological Characteristics and Associated Elements of Bauxite Deposit in Yushan,Xin an County
The geotectonic locates in the northwestern segment of Mianchi Queshan depression fold fault beam in the south area of North China landmass for Yushan bauxite ore in Xin an county. The deposit is in Benxi group of Upper Carboniferous system,the deposit is diaspore type bauxite,and the reserve is large. The deposit belongs to the ancient weathering crust type ore.Comprehensive exploration and evaluation confirmed the paragenesis and association of light rare earth(LREO),rare elements(Li,Rb,Nb),dispersed element( Ga),ferrous metals( Ti,V)and other useful elements. In Bayer producting process of alumina production,Ga,Li,V,Rb can be enriched in the mother liquor of alumina. LRE,Sc,Nb and Ti can be enriched multiply in crude red mud. Therefore,research can be strengthened for comprehensive recovery of valuable components paragenetic and associated in bauxite deposits.
