centration by flotation carried out with a fraction of iron ore made up of the magnetic separation tailing The study into the recovery of this material carried out in a pilot unit scale had as its main objective the production of an iron concentrate meeting standards required for commer cialisation ie Fe and SiO2 content of around 66 andTaconite is a low grade iron ore When the high grade natural iron ore was plentiful taconite was considered a waste rock and not used But as the supply of high grade natural ore decreased industry began to view taconite as a resource Dr EW Davis of the University of Minnesota along with other scientists and engineers conducted years

Maximizing the recovery of fine iron ore using magnetic separation by M Dworzanowski Synopsis The beneficiation of fine iron ore will increase in importance in the future because most new iron ore resources will be in the form of lower grade ore deposits that will require liberation of iron ore minerals at Iron processing use of a smelting process to turn the ore into a form from which products can be fashioned Included in this article also is a discussion of the mining of iron and of its preparation for smelting Iron Fe is a relatively dense metal with a silvery white appearance and distinctive
