magnetic separation hematite taconite

Jun 04, 2018· Davis’s low intensitymagnetic separation processworked well ontaconite’smagnetite ores, but thosemagnetite reserveswill eventually be depleted. What’s next? NRRI is developing a process that recovers two other valuable iron oxide minerals --hematiteand goethite -- using a natural pH flotation process.

The taconite extends the entire NE-SW extent of the Property, 2.2 km and beyond, and occurs over a width of 800 m to 1 km in a NW-SE direction. The taconite is folded and its true thickness varies throughout because of tectonic thickening, erosion and possibly the original basin topology.

Jan 31, 2018·Hematitehas unpaired electrons that cause itsmagneticproperties. It is paramagnetic because it has only ferric ion (Fe 3+).The electron configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present. Therefore,hematitecan be separated from a mixture using high-intensitymagnetic separationmethods which usemagneticfields with intensity ranging from 0.02-4 ...
