| Abstract: |
| A combined process flowsheet including pre-desliming-high gradient magnetic- magnetic concentrate regrinding-reverse flotation was adopted to handle a high-mudded and high-silicon hematite ore.The results indicate: the run-of-mine ore can effectively eliminate the effects of clay and other shale minerals by spiral chute desliming,Slon Ring high-gradient magnetic seperation after regrinding,the study used cation collector to desilicate in reverse flotation.While the run-of-mine ore has 12.43% of Fe, the iron concentrate with Fe content of 51.28% and recovery rate of 38.74% was obtained. |
