This work investigated the use of a wet high intensity magnetic separation (WHIMS) in conjunction with gravity pre-concentration steps (Knelson and Falcon centrifugal concentrators) to beneficiate a rare earth ore. The results of these separation steps are related to the magnetic properties of RE minerals, based on literature and …
This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron …
Magnetic separation experiments of ultrafine iron ore particles under different oleate and colloidal magnetite concentrations validated the molecular level analyses, thus achieving successful experiment–theory nexus based on a sound theoretical background explored beforehand by computational simulations.

In this study, high-grade ferronickel concentrates were obtained through a carbothermal reduction and magnetic separation using laterite nickel ore and anthracite as raw materials.
In order to produce high-grade iron ore concentrates a magnetic-gravity method has been developed for separation of magnetite ore. It provides separation of mineral complexes according to magnetic properties, density and size.
REE ore deposits around the world are scarce and those that have been identified but remain unexploited need to be developed to supply future demands. In this study, the Khalzan Buregtei deposit located in western Mongolia was studied with the aim of upgrading low-grade REE ore via magnetic sepa-ration techniques.
To address this, dry magnetic separation is an alternative approach to separate these iron-bearing gangue minerals from the chromite. This work investigated on the application of different dry high-intensity magnetic separators to separate the chromite grains from ferruginous chromite ore deposits of India.
However, it is very difficult to enrich this ore, because of the poor beneficia- bility of silicate and dispersed distribution of scandium minerals. This paper has focused on magnetic separation processes for the pre-concentration of poor magnetite associated with scandium oxide ore, according to the composition and occurrence state of scandium.

Magnetic separation, thanks to its advantages of large processing capacity, low operation cost, high efficiency and applicability, and environmental friendliness in comparison to other separation methods, can be widely considered for use in the field of mineral processing.
Nevertheless, when reduction roasting–magnetic separation is used to treat laterite nickel ore with low nickel content, increasing the dosage by approximately 8–20% inevitably reduces equipment life and increases cost (Liu et al.,2021). Therefore, improving the grades and recoveries of iron and nickel is of major significance.
