The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.

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 …

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 …

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 ...

Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Values obtained from ground magnetite are compared to pellets produced from the as-received magnetite and hematite concentrates. Wet-drop and dry-crush values marginally increased after dry-grinding the magnetite concentrate. Wet drop increased from 3.5 to 4.0 drops, while dry-crush increased from 10.1 to 16.0 N/pellet.

difference between hematite and magnetite iron ore. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons) Haematite is a slighty lower quantity of iron of about 60%-70% but the Magnetite ore is a finest high quality iron with 70% iron.
