It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.

Magnetite (Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin.Magnetite has an inverse spinel structure and is partly altered in near-surface environments to hematite (Waychunas, 1991) or kenomagnetite.Hematite is commonly thought to form from oxidation of magnetite in the …
When not broken, hematite oolites appear to be red, well-rounded sand grains or may be mistaken for lithified fish eggs. In Our Earth: The Geologic Importance of Hematite. ... Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In ...
Synthesis of Hematite Crystals from Natural Iron Sand: The Influence of Heating on Optical and Magnetic Properties P. Suardana1*, M. Sumadiyasa1, Ni Wayan Sudatri2, W. G.
