| Abstract: |
| An investigation on mineral composition,dissemination characteristics,size fraction of Henan bauxite was carried out *"Native grain size of diaspore in the ore is fine *"Rich aggregates of diaspore are formed by various geological effects Their average ratio of aluminium and silican is higher than 37,and the aggregates with grain size of over 0 074mm account for 58 73% And the shape factor and selective crushing and liberation of minerals were studied The influence of these features on de silicon in ore dressing,grinding liberation,reduction of iron and titanium content and alumina production are expounded in this paper |
