In some places reduction roasting of the low grade hematite ore is done to convert it into magnetic ore before the application of the magnetic separation method for the ore beneficiation. Another method which can be employed is the use of a dense medium in a gas-solid fluidized bed for the enrichment of iron ore.

Pulsating high-gradient magnetic separation (PHGMS) of fine hematite from tailings was studied using a pilot PHGMS separator to investigate the possibility of its application in industry.
In contrast, the Rq of hematite adsorbing with DDA increased to 12.3 nm, making it rougher. Typically, hematite particles with higher roughness performed superior during flotation [26], indicating that LPDC is more effective in separating quartz and hematite compared to DDA.
Since hematite and dolomite particles have different densities, 5.25 and 2.87 g/cm 3, respectively, and that method requires less energy, this paper aims to concentrate hematite from a zinc mining tailing composed of 3% SiO 2, 7% Fe 2 O 3, and 90% CaMg(CO 3) 2 through gravity separation using shaking table.
separation (spiral concentrator, jigging, heavy media separation) used to separate the gangue minerals from hematite are considered to be expensive and are not environment-friendly due to higher water consumption.

-During the gravity separation process, the powdered hematite ore is washed by an upward stream of running water. The lighter particles of gangue get washed away with water. The heavier ore particles are left behind. Thus, the gravity separation process is used for the concentration of hematite. Thus, the correct option is (B) hematite.
