| Abstract: | An iron grade in an iron ore from mainly in the form of oolitic hematite-limonite ore. Sichuan Province is about 38%, and the iron ore is While a phosphorus content is up to about O. 65%. Then the roasting reduction-magnetic separation of the ore was done in the test. The test achieves an iron concentrate with an iron grade of over 60%, an iron recovery of above 70%, and the phosphorus content reduces to 0.3%. It has solved the key problem of the iron ore containing high phosphorus and the iron ore can be used now. |
