Abstract:
     The present invention relates to a cyclone suspension flash magnetizing roast-magnetic separation method for difficult-separable ironoxide ore. Its concrete steps are as follow: firstly, roasting the powdered difficult-separable ironoxide ore granules or fire-ground strong-magnetically-separated chats in the separation process under the condition of high-temperature reduction atmosphere and cyclone suspension fluidized state to make them be quickly dynamically reduced into magnetite within 5-100 sec. then adopting weak magnetic separation process to obtain high-quality acceptable iron headings.
