Abstract
The paper describes the characteristics of the technological mineralgy of Nanfen Hematite ore,beneficiation test research and the results of enlarged continuous test of the flowsheet consisting of the staged grinding,low intensity magnetic separation,high intensity magnetie separation,anionic reverse flotation.The continuous test obtained an iron concentrate having a grade of 65.84% and a recovery of 91.13%,providing a reliable basis for the Hematite ore comprehensive utilization and the industrial design the concentrator.
