Abstract: High alumina clay mineral is associated with bauxite and refractory clay mineral,the exploration and utilization has a long history with rich resources in our county.Because before the high alumina clay ore is a refractory clay ore,resulting in high alumina clay mineral resources is not clear,excellent quality is not used enough.This paper analyzed the Geological-exploration-norm relationship of the High alumina clay mineral between bauxite and refractory clay mineral,and explained the reasons for its reserves is unknown or not used enough.The author proposes to establish a geological-exploration-norm of high alumina clay mineral,define and estimate the reserves alone while geological exploration.It will cause more attention and use high alumina clay mineral correctly in the future.
