Beneficiation test of the low-grade nickel ore has been carried out.As showed by the results:by using grinding with fineness of-0.074mm 85%,first anti-flotation off the mud,then tailings after mud off have been roughed,twice coarse sweeping selection,three times precise selection process;choosing sodium carbonate,2#oil,CMC,copper sulfate,butyl xanthate and J-622 as flotation reagents;indicators of test are as follows:the grade of nickle in raw ore is 0 .1 8%,in flotation concentrate is 3 .1 5%,in folating tailings is 0 .1 1%,in against flotation products is 0 .1 9%,and recovery rate of concentrates nickel is 3 9 .1 7%.This result can provide a techni-cal basis for ore optional evaluation.
