摘要
国外某低品位铬矿石含Cr2O314.02%,为了合理开发利用该资源,本文以该铬铁矿为研究对象,在试验室采用磁选-重选联合工艺流程进行试验研究。试验结果表明:弱磁-强磁-弱磁精矿再磨摇床重选-强磁精矿分级-摇床重选工艺流程可以获得Cr2O3品位45.12%,回收率65.08%的指标。
A kind of foreign low grade chrome ore with the grade of Cr203 at 14. 02%, in order to rationally develop and utilize the resources, treat the chrome ore as the research object in this paper and using magnetic separation-gravity separation joint process carry on the experimental study in the lab. Experimental results show that low intensity magnetic separation-high intensity magnetic separation-low intensity magnetic ore concentrate regrinding table concentrator gravity separation-high intensity magnetic concentrate grading-table concentrator gravity separation process can obtain the grade of Cr2 03 at 45.12%, recovery rate of 65.08%.
