Abstract: This paper describes the structure characteristics, working principle and application range of the new type magnetic separator, and application in nonmetallic mineral resources separation. At the same time, the effectiveness and rationality in separation of coarse weakly magnetic ore are proved . The new type of magnetic separator has advantages of low energy consumption, simple operation Principle, easy maintenance, etc. It's can be widely used in the field of non-metallic minerals purification and weakly magnetic minerals metal further concentrated.
