Abstract: The feasibility study was made on the beneficiation of Hainan Danzhou oolitic limonite ore grading 40.15% mainly by wind separation.An iron concentrate grading 56.55% at a recovery of 84.50% was finally obtained with the help of roasting -magnetic separation.The process can avoid the serious sliming of limonite ore processing to some extent, and save the water and energy.

Key words: Oolitic limonite ore, Wind separation, Roasting -magnetic separation
