The magnetic ore stays on the belt, while the gangue slides off. By eliminating non-magnetic impurities, this process is utilised to concentrate magnetic ores of iron such as magnetite and chromite and manganese (pyrolusite). A magnetic separator is used in this procedure. A magnetic separator is made out of two rollers and a leather belt.

On this premise, this brief review is focused on investigating magnetic separation process applications in the beneficiation/recovery of HMs.

The flowchart of the multi-step magnetic separation process, presented in Fig. 7, shows the pre-concentration production process flow for the two main products viz., vanadium-magnetite and ilmenite, and the total yield, content grade, and the recovery results for vanadium, titanium, and iron.

The magnetic tube will then be utilized for magnetic separation to produce the magnetic concentrate and magnetic tailing.Initial experimental conditions: a roasting time of 30 minutes, a reducing gas (CO: H2 = 1:3) concentration of 30%, a finesse of grinding with 80% particles finer than 0.038 mm, and a magnetic field intensity of 1200 Oe.

Magnetic separation is a physical separation process that relies on the different magnetic properties of components in a mixture. By applying a magnetic field, magnetic particles are separated from non-magnetic ones based on their magnetic susceptibility and volume, leading to efficient separation of substances.

slow cooled, crushed, and sent to the Magnetic Concentration Plant at the Rustenburg Base Metals Refinery (RBMR). Here, the magnetic PGM-containing fraction is removed and sent to the PMR, while the remaining material is treated at the RBMR to recover nickel, copper, and cobalt. At the PMR, the PGMs are separated and refined to produce pure metals.

resulting non-magnetic fraction is then further upgraded by gravity concentration, and followed by conventional dry separation techniques to create the higher value zircon and rutile products. In Figure 2b, the wet process consists exclusively of gravity concentration followed by a dry plant for fractionating the HMC into various products. In some
