| 摘 要： | 铝土矿选矿精矿粒度对精矿脱水过滤及拜耳法生产氧化铝具有重大影响。通过对铝土矿选矿精矿铝硅比的要求，一水硬铝石嵌布状态的研究，发现矿石中存在的大量粒度较粗的一水硬铝石富集合分配 ，并测量了其粒度（工艺粒度）。并对磨矿产品的富集合体解离度进行了互分析计算，精矿粒度可放粗至７５％～０．０７５ｍｍ左右。 |
| 关 键 词： | 铝土矿 一水硬铝石 富集合体 选矿 精矿粒度 |

| Abstract: | The grain size of bauxite concentrate during the beneficiation of bauxite has key effect on the dewatering and filtration of the concentrate and Bayer alumina production.By study of the requirement of Al/Si ratio and insertion condition of diaspore,it is found that a lot of coarser rich diaspore aggreagate exists in the ore and the grain size (process grain size) of the aggregate is measured.The dissociation of the rich aggregate during grinding is also measured.The grain size of the concentrate can be enlarged to 75%-0 075mm. |
| Keywords: | bauxite diaspore rich aggregate rich intergrpowth |
