A flowsheet for magnesite ore processing is shown in Figure 1 that is generally accomplished by crushing/screening, hand sorting and dry magnetic separation. In addition to these operations, froth flotation, leaching, agglomeration, coagulation or fluctuation methods can be also used.
The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron …

The low-grade iron ore fines contain weakly magnetic iron minerals such as hematite and siderite, which could not be separated effectively by low-intensity magnetic separation. Therefore, the ore fines were magnetized by magnetization roasting, then low-intensity magnetic separation was used to enrich magnetic iron minerals.

Re-drawn figure Dry low-intensity magnetic separators (DLIMS) are generally employed to: – upgrade iron ores containing relatively large particles and strongly magnetic minerals – separate iron pieces from steel mill slags and blast ...
As the particle size fraction decreased from 4.0 + 2.0 mm to 0.5 + 0.1 mm, the recovery by dry high-intensity magnetic separation (DHIMS) increased from 20% to 70% of total rare earth oxide (TREO) while the enrichment ratio reached 2.8 from 1.3.
Magnetic separations were realized on the electromagnetic separator (XCGS-73, magnetic tube, Jiangxi Walker Machinery Co., Ltd., Ganzhou, China) with a magnetic field intensity of 3.0 KOe, which is specified for the wet mode of separation. Process conditions: grinding time of 20–40 min; magnetic current of 2.5–4.5 A. 2.1.
Magnetic separation utilizes the force of a magnetic field to produce differential movement of mineral particles through a magnetic field; this and the fundamental differences in the magnetic susceptibility of minerals constitutes the basis of separa tion to effectively obtain purification or concentration of mineral products. In

For a dry high-intensity drum magnetic separator (DHIDMS), its magnet system was generally designed into an extruding magnetic structure, to improve the magnetic field intensity and gradient on the drum surface; and in this way, it is applicable for the separation of weakly magnetic ores and for the purification of non-metallic ores, …
Moreover, since biomaterials have a relatively low intrinsic magnetic susceptibility, there is substantial contrast between tagged and untagged material, which enables a high degree of selectivity. In conventional magnetic separation systems rare-earth magnets or electromagnets are used to produce a non-uniform field distribution throughout the
The difference in the magnetic properties of minerals is the basis for magnetic separation. All minerals can be generally classified as ferromagnetic (strongly magnetic), paramagnetic (weakly magnetic) or diamagnetic (non-magnetic). Magnetic separation can be conducted dry or wet.
