biomass / low grade iron ore mixed in the ratio of 1:10 in a reducing environment was heated in a controlled air condition to increase the magnetic susceptibility of iron in the ore. The magnetic portion of the resulting product was separated using a horse shoe-magnet. This resulted into concentrating the ore from 45.6% - 53.1 % to 76.3%- 82.2%.

Magnetic separation has two major applications in mineral processing plants: The removal of tramp iron (which would deleteriously affect subsequent processes) from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.

Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...

Probably the biggest financial failure of Edison's career was the magnetic ore-separator. The idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lower-grade ores. This would mean that abandoned mines could be profitable ...

Jun 30, 2019· Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
