摘　　要：南非某铬铁矿尾矿含Cr_2O_3品位23.07%,为了合理开发利用该资源,提高该资源的利用率,本文以该铬铁矿尾矿为研究对象,采用全粒级摇床重选工艺流程、全粒级分级重选工艺流程、磨矿单一重选工艺流程和磨矿-分级-重选工艺流程四种方案对该试样进行试验研究,最终磨矿-分级-摇床重选工艺流程可以获得Cr_2O_3品位46.36%,回收率81.21%的较好指标。The CrzO3 grade of a chromite ore tailings in South Africa is 23.07%. In order to develop and utilize re-sources reasonably and improve the utilization ratio of resources,this paper takes the tailings of the chromite ore asthe research object. Experimental study was carried on byusing four schemes of full fraction shaking table gravityseparation process, full fraction classification gravity separation process, grinding-gravity separation process andgrinding-classification-gravity separation process. Good beneficiation indicators with Cr2O3 grade of 46.36% and re-covery of 81.21% can be obtained by using grinding-classification-shaking table gravity separation process.
