1994-5-1 When minerals have very similar susceptibilities, or similar magnetic moments in the presence of a field, other magnetic properties may be exploitable to achieve selective separation. Two species with different coercive forces may be separated by applying an alternating magnetic field, with peak value below the coercivity of one mineral and ...

2002-2-13 Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet.

1992-3-1 The Frantz Isodynamic, introduced in the early 1930s, is the most efficient magnetic separator for the discrimination of minerals with fieldindependent magnetic susceptibilities. The isodynamic field, generated by a bipolar magnet with special pole tip profiles, provides the constancy of the product of the field and the field gradient.

Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.

2014-7-1 Many RE minerals are found alongside low specific gravity gangue minerals thereby permitting the use of gravity separations to concentrate the heavy value RE minerals. Magnetic separation is used primarily to remove ferromagnetic gangue minerals as well as to separate individual paramagnetic rare earth minerals.

2018-9-6 magnetic separation. The application of SEM-based image analysis data to magnetic separation was inter alia carried out by Leißner et al. (2016b) [15]. The magnetic susceptibility of different minerals is one major determining parameter influencing the results of magnetic separation. The iron content in minerals shows a big

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research.

Coal is also classified as a weakly diamagnetic material which contains minerals associated within the organic matrix, some of which may be iron minerals. Magnetic separation may be used for coal beneficiation when the gangue minerals contain such iron phases, however their very weak magnetic susceptibilities would require strong magnetic field ...

2018-5-1 Laboratory investigations on the possibility for magnetic separation of sulphide minerals are reported. A survey of several sulphide ores and flotation concentrates shows that magnetic separation in most cases is not a suitable primary method of beneficiation. However encouraging results have been obtained in concentrate purification. Traditionally magnetic separation
