山东会宝岭铁矿JCTN提精降渣磁选机选矿试验

摘要

为探究JCTN提精降渣磁场机在山东会宝岭铁矿的应用效果,进行了JCTN提精降渣磁选机磁选试验.结果表明:1、采用JCTN提精降渣磁选机用于一段磨后磁选作业,在粒度为-0.074 mm 52％的情况下,可以直接将精矿品位提到66％以上,省掉二段磨以及后续磁选作业;2、将一段磨机处理量从350 t/h提高到500t/h,放粗JCTN提精降渣磁选机给矿粒度,通过与高频筛的配合使用,可以将精矿品位提高到66％以上,节省二段磨矿成本.%In order to explore the application effect of JCTN RCG-DDC permanent magnetic separator in Huibaoling iron mine,we use the JCTN RCG-DDC permanent magnetic separation done the separation test.The resuhs show that adopting JCTN RCG-DDC permanent magnetic separator for magnetic separation after first mill,under the condition that-200 mesh materials account for 52％,the concentrate grade can be improved directly to over 66％,saving the second mill and following magnetic separation,improving the processing capacity of first mill from 350 t/h to 500 t/h.Broadening the mineral feed size for JCTN RCG-DDC permanent magnetic separator,and cooperating with high frequency screen,the concentrate grade can be improved tover 66％,saving the milling cost of second stage.
