Abstract: The total iron grade of a lean Oolitic hematite is 32.16%. Oolitic iron mineral hematite complex relationship with the gangue minerals. The main structure is Oolitic structure. The second is disseminated structure. Iron and silicate content of siderite accounts for 21.99%, are refractory ore. Deal with the deep reduction process to achieve the effective concentration of iron:-2mm ore in the reduction temperature for 1200℃, reducing time for 120min, the ratio of coal mine for 2 through the deep reduction, after a period of grinding, two magnetic separation were gotten as follows:fine mineral availability rate up to 30.12%, iron grade above 92.18％, iron recovery above 90.45％.WT
