红土型三水铝土矿的一种新分类方法

由于已知国内的红土型三水铝土矿矿床均为小型,且矿石质量也偏差,多为小规模开采利用,而国外多为大型—特大型矿床,质量也好.笔者长期在境外开展红土型三水铝土矿的资源勘探和资源评价工作.在结合矿山开采的选矿工作和生产氧化铝的拜耳法工艺,对红土型三水铝土矿按照边界品位即是否需要洗矿,提出了全新的分类方法.

A new classification method of lateritic-gibbsite type of bauxite deposit

As known lateritic-gibbsite type of bauxite deposit is a small scale in China.The ore quality is not good enough,and the most mines are in small size.But there are much more bauxite deposits of large or su-per-large scale abroad,and ore quality is much better.The author has carried out the research of resource exploration and resource evaluation of lateritic-gibbsite type of bauxite deposit for many years.Combined with mineral separation of mining and the Bayer process of alumina production,this article has proposed a new classification of lateritic-gibbsite type of bauxite deposit in respect to whether the ore of the cut-off grade need to be washed or not.
