摘要
对河南铝土矿的矿物组成、嵌布关系、粒度特性进行了研究。矿石中一水硬铝石自然粒度细小 ,在各种地质作用的影响下 ,形成了一水硬铝石的富集合体 ,其铝硅比平均在 37以上 ,粒度大于 0 .0 74mm的占 5 8.73%。研究了矿物的形状因子、选择性碎解等工艺性质 ,并阐明了这些性质对选矿脱硅、磨矿解离、除铁降钛、氧化铝生产的影响。
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
