Another lump hematite beneficiation project has been completed in 2024. The Plant Video Link: BAS® Lump Hematite Beneficiation Plant with High Intensity Perm Roll Magnetic Separators (youtube.com).
Mineralogical and beneficiation studies are completed by BAS and related laboratory to find the right fraction sizes and magnetic intensities under the BAS mining engineering dicipline.

Increasing demand for quality metalic ores has led to beneficiation of even lean-grade ores, fines, slimes, and wastes. Commercial acceptance of ore depends on up-gradation of iron values by separating impurities such as alumina, silica, alkali, and phosphates. Efficient utilization of low-grade ores calls for the development of efficient beneficiation processes,which are cost-effective and energy-efficient. Use of dry magnetic separation could prove to be a novel alternative as compared to other physical methods.There are different minerals in nature which are utilized for the extraction of steel.

There is a rapid progress in mining industries along with looking for the technologies that aim to turn mining into an environment sustainable and cost effective activity. Thus, the development of dry mode of magnetic separation is an essential outcome, which is designed to utilize high intensity magnetic field for the separation of paramagnetic minerals. In dry magnetic separation process, the separation of paramagnetic particle from nonmagnetic occurs depending on the difference in magnetic susceptibility, particle size, and density of paramagnetic particles along with machine operating and design variables. Furthermore, the use of BAS® High Field Intensity Perm-Roll Magnetic Separators (Perm Roll Magnetic Separators – BAS® (bas-tr.com)) for the separation of paramagnetic minerals could prove to be a novel and advantageous alternative as compared to other physical methods. Since, the separator requires low energy and less floor space along with the magnetic field strength of 1,5 T can be produced. The advantage of having high magnetic force is to separate magnetic particles at higher feed rate. Besides, the equipments are more effective, selective and can be easily attuned to feed variations, but are particularly effective to separate fines coarser than 0,075 mm with no water and less power consumption as compared to wet high intensity separation. It also offers environmental benefits (no water consumption) over physicochemical methods which includes gravity separation (jigging, spiral concentrator, heavy media separation) and froth flotation are used to segregate the gangue from high density (hematite) minerals.
