Beneficiation of mineral sands: a practical outlook

Concentration is performed by various methods of exploiting the physical and chemical behaviors of the feed materials to the process plant. Beneficiation processes mainly used for heavy mineral sand deposits are: (1) gravity separation, (2) magnetic separation, (3) electrical separation, (4) hindered settling, and (5) flotation (Table 5.4).

Difference Between Magnetite and Hematite | Definition, …

Hematite has unpaired electrons that cause its magnetic properties. 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, hematite can be separated from a mixture using high-intensity magnetic separation methods which use …
