The results ofprocessingm ineralogy test show that themainmetallicm inerals are titanomagnetite, and a few hemati tized magnetite and lmi onite are coexisted; and it has a good natural liberation degree. For runofm ine w ith TFe of 30. 52 , vanadiumtitanium magnetite concentratew ith the yield of 45. 0 , TFe grade of 58. 04 , and recovery of 86. 27 is obtained undergrinding fineness of - 0. 074mm 80. 0 by the flowsheet of one rough lowintensitymagnetic separation and one cleaning lowintensitymagnetic separation. This research provides a basis for the development and utili zation of beach Ferro resources of this type.
