Abstract: In order to explore the separation effect of copper flotation-iron magnetic separation pro⁃ cess and iron magnetic separation-copper flotation process on an iron-copper ore in Inner Mongolia，a com⁃ parative test of two different processes is carried out on the basis of ore properties.The experimental results show that the copper concentrate with copper grade of 25.75%，copper recovery of 94.03%，iron content of 29.04% and iron recovery of 0.69%，and iron concentrate with iron grade of 69.09%，iron recovery of 89.00%，copper content of 0.015% and copper recovery of 3.06% can be obtained by two-stage continuous grinding-copper flotation-iron magnetic separation process under the conditions of one-stage grinding fine⁃ ness of -0.075 mm 60%，regrinding fineness of -0.075 mm 65%，magnetic field strength of 80 kA/m，flota⁃ tion operation collector Z-200，inhibitor lime.
