摘　　要：新安县郁山铝土矿,大地构造位置处于华北陆块南部,渑池—确山陷褶断束的西北段。赋矿层位为石炭系上统本溪组,矿石工业类型为一水硬铝石型铝土矿,铝土矿资源量为大型规模。通过综合勘查、综合评价,确认该矿属共伴生有轻稀土(LREO)、稀有元素(Li、Rb、Nb)、分散元素(Ga)及黑色金属(Ti、V)等有用元素的古风化壳型铝土矿床。在拜耳法生产氧化铝的过程中,Ga、Li、V、Rb富集于氧化铝的母液之中,LRE、Sc、Nb及Ti成倍富集于生赤泥之中。因此,加强对共伴生于铝土矿中有用组分综合回收工艺研究,具有重要的经济意义。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 .
