| Abstract: | The hematite in Qingzhen area of Guizhou is oolitic hematite ore,and the barren rock mainly is silicon and aluminum.The oolitic hematite ore tests were conducted by gravity separation,magnetic separation and magnetic roasting-magnetic separation.The results showed that the magnetic roasting magnetic separation-flotation process could achieve better indexes.It could get an iron concentrate with a grade of 61.27%,a recovery of 87.39%,and the potassium content in iron ore fell to 0.20%. |
