Advancement and Developing Trend of Iron Ore Concentrating

It is urgent to make innovations on iron ore concentration in terms of the China iron resources property and the situation of Chinese economic development.In this paper,the advancement on the mineral processing technology of magnetite and hematite in our country,especially on the development of magnetic separators and the improvement of reverse flotation techniques,were mainly introduced.It was suggested that in order to im- prove utilization technologies for various iron resources the further research will be required on the processing of poor,complex and hard-concentrated iron ores.
