Hematite is weak magnetic. It contains mainly Fe2O3, concluding Fe70 %, O 30%, which is the major iron ore. Based on the test report of ore provided by customer, we designed this hematite dressing technics: three stages crushing----one stage milling----two stages magnetic separation---- dehydration----final product. Using this technics, we can improve the Fe content from 40% up to 65%. And the ferric oxides recovery ratio is about 80%.
Hematite beneficiation process
1.Hematite ore crushing: in this stage there are also three steps, the hematite ore may go through primary crushing, secondary crushing and fine crushing. Hematite primary crushing equipment includes gyratory crusher, jaw crusher, hammer crusher etc. Hematite secondary and fine crushing plants mainly include cone crusher, ball mill, vertical mill, ultrafine mill etc.
2.Main operation steps in the whole hematite beneficiation process include sorting, gravity separation, floatation, magnetic separation, electrostatic separation, chemical mineral processing etc. There are many plants involves in hematite beneficiation process, such as flotation equipment, magnetic separator, electrostatic separator etc.
3.The treatments of refined hematite mineral include dehydration, tailing disposal, backwater etc. Thickener and dryer are important plants in this stage.
