Experimental study on beneficiation technology of a magnetite-oxidized iron ore mixture from Indonesia was carried out.The results of grinding-low intensity magnetic separation experiment showed that when grinding size was 70.67%-74 μm and magnetic intensity was 159.2kA/m,the iron concentrate with a grade of 65.46% and a recovery 0f 52.70% was obtained.Adopting a process of low intensity magnetic separation-high intensity magnetic separation,the comprehensive iron concentrate with a yield 0f 68.32%,a grade of 61.61% and a recovery 0f 79.04% was obtained.Another process of low intensity magnetic separation-table concentration could get the comprehensive iron concentrate with a yield 0f 59.63%,a grade of 63.65% and a recovery 0f 71.27%.
