Generally, the hardness of magnetite is between 5.5 and 6.5, and the specific gravity is between 4.6 and 5.2. This ore is widely distributed in nature and has abundant reserves. However, the pure magnetite in the surface of the earth's crust is rare, because magnetite is a non-high-valence oxide of iron, so oxygen or water should continue to ...

As shown in Table 1, Fe was the main recovery component with a content of 24.27%, and SiO 2 was the main impurity with a content of 60.39%. The analysis of Fig. 1 shows that hematite and magnetite are the main iron-bearing mineral in raw ore. Gangue mineral was mainly quartz. The dissociation degree and intergrowth relationship between hematite, magnetite and gangue minerals …

Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores (DSOs) generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products.Low-grade hematite ores require additional beneficiation to achieve the desired iron …

Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

The grinding behavior of the as-received (5 pct moisture) vanadium-titanium magnetite concentrates in a damp mill was investigated in this paper. A grinding kinetics equation was established based on a population balance model using size distribution data obtained from a laser diffraction technique. X-ray diffraction results show that a loss in crystallinity occurs when the grinding time is ...

hematite revealed quartz particles but no magnetite The absence of magnetite is also indicated by the measured values of saturation magnetization J, s which ranged between 02 and 05 A m kg see2 y1 Table 2 If these samples would be contaminated by magnetite, Js would be larger than the listed value for J of hematite ;04 A m kg in Hunt.

Then, the particle size of the strong magnetic ore has to be reduced by the grinding operation to a certain range before sent to magnetic separators. The grinding operation uses the two-stage ...

The liberation characteristics of magnetite and hematite guide the grinding and separation of ore. The liberation of magnetite and hematite was 20.58% and 2.28%, respectively . The intergrowth composed of magnetite-hematite-gangue was the main form of existence, which accounted for 58.68% and 64.84% in the magnetite and hematite, respectively.

the same as those of hematite[5-7). The aggregation between magnetite and hematite therefore can not be explained solely on the basis of their surface properties. However, considering the fact that aggregation is normally obtained if the zeta potential is less than 14 mY [8), the zeta potential values of magnetite and hematite( = -30 mY as

There are certain differences between hematite concentrates and magnetite concentrates; plants may be optimised to use one over the other. Magnetite has a slightly higher Fe content as a mineral (72.36% vs 69.94% for hematite), and its ferromagnetic properties allow for relatively easy concentration using magnetic separation.

12%Electron backscatter diffraction (EBSD) has been used to investigate the microstructure and texture-based features of an industrial tertiary oxide scale formed on a micro-alloyed low-carbon steel from a hot strip mill.
