Jan 28, 2012· This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than hematite; therefore, its quality is higher. Apart from that, in colours too, there is a difference between magnetite and hematite. Magnetite is black in colour, but hematite .
Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from runofmine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.
Hematite can also occur as a result of volcanic activity. Claysized hematite crystals occur as a secondary mineral along with oxyhydroxides, such as goethite, or other iron oxides as a result of the weathering process in soil. The most common deposits of hematite are sedimentary deposits, such as the Lake Superior district in North America.
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.

Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Aug 07, 2014· The oxidized magnetite (Fe3O4), which resulted in formation of hematite (Fe2O3), was then reduced by using continuous stream of CO (5% and 10%) with N2 balance. The rate of oxidation was determined by the oxygen weight gain. Analysis of the data indicated that the oxidation behavior followed a twostage process.

The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water. Magnetite for coal washing must be of overall high purity and be devoid of contaminants, such as hematite, sulphides or other minerals.
Karara comprises a largescale, longlife magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (3436% Fe) than hematite ore (5864% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to .

Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
Typically, hematite is mined by open pit mining. Overburden is removed, then the ore is mined from an everdeepening hole. The mineral and rock is first stripped by blasting the rock with explosives and removing it with enormous trucks with capacities over 150 tons. The ratio of mineral to rock can be quite large up to to 1 for hematite.
