Several minerals belonging to different groups are also listed in Table 2.1 [7, 8]. There is a strong correlation between minerals' magnetic susceptibility and their chemical compositions [9]. Generally, besides reducing water consumption, the use of dry magnetic separation methods also has other benefits. In dry magnetic sepa-

Simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance, as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals. In this study, we attempt to increase the apparent sizes of target mineral particles, and improve …

Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation technologies. In …

The separation of coal from other materials is a leading use case for magnetite assisted heavy media separation. The process by which a material such as coal is 'cleaned up' by way of having gangue or other valueless components removed, thereby leaving the desired mineral and a waste stream, is called beneficiation.

The separation is between economic ore constituents, noneconomic contaminants and gangue. Magnetite and ilmenite can be separated from its nonmagnetic RFM of host rock as valuable product or as contaminants. The technique is widely used in beneficiation of beach sand. All minerals will have one of the three magnetic properties.
