For ore minerals of iron oxide ore is refractory, its fine grain size, mineral composition is rather complicated, and complicated relations between the characteristics of mineral inlay; achieve comprehensive recovery of the iron ore resources are the main contents of this issue and difficult. Through the use of the ore crushing, grinding, low intensity magnetic separation, high intensity magnetic separation, gravity separation, flotation and chemical beneficiation beneficiation methods such as tests carried out on Process Mineralogy of ore and beneficiation process of carrying out the relevant conditions trial and conducted a joint process of several beneficiation test. And obtained the following results: (1).Determine the high grade hematite, oxidized heavy, and have a clear understanding ofhe ore composition and gangue mineral composition, texture and structure, embedded fabrict characteristics crushability grindability (2).Mineral Processing by experimental research on a variety of beneficiation comprehensive comparisons, identify the reasonable process. And finally finalize the gravity separation - magnetic roasting - and then grinding - low intensity magnetic separation process and the gravity separation - magnetic roasting - and then grinding - Magnetic Separation - Pickling (washing) process are more suitable for the kind of iron ore mine material recovery. Can be get ≥ 60% grade iron ore products. The research acheved the comprehensive recovery of the iron, the final product meet the requirements. for sorting the mine provides a feasible and reasonable process, with a more
