magnetic separation iron from hematite

Magnetic separation of hematite and limonite fines as hydrophobic .Magnetic separation of weakly magnetic iron mineral fines in the form of flocs, which is termed Floc Magnetic Separation (FMS) process, has been studied in the present work, in order to find a substitution for high-intensity or high-gradient magnetic separators to treat the ores with weakly magnetic iron minerals in the fine.magnetic separation iron from hematite,magnetic separation iron from hematite,Processing of Lean Iron Ores by Dry High Intensity Magnetic .Dry high intensity magnetic separation (DHIMS) is investigated to process a lean hematite ore. It was found that the feed particle size and the drum rotation speed have significant influences on the separation performance, and a magnetic concentrate assaying 36.22% Fe with 75.97% recovery is achievable from the ore.

Iron ore - Wikipedia

The thermodynamic barriers to separating pure iron from these minerals are formidable and energy intensive, therefore all sources of iron used by human industry exploit comparatively rarer iron oxide minerals, primarily hematite. Prior to the industrial revolution, most iron was obtained from widely available goethite or bog.
