Abstract

Technical of magnetic-flotation separation is mature for magnetite and hematite mixed quartz vine-type iron ore.In light of the fact that the ore has the characteristics of fine-grained dissemination size of minerals and low iron grade,the process of grinding of rough concentrate was adopted for purpose of achieving better grade of concentrate and flotation feed grade.As a result,from a feed containing Fe 22%,the product of Fe concentrate of low intensity magnetic separation grading over 65%,Fe concentrate of reverse flotation grading over 58%,Fe at a comprehensive recovery of over 50% were obtained.
