Hematite is colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron.Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rust-red streak.

Magnetite resembles a number of other metal ores, but it is the only common mineral that exhibits magnetism. So magnetism alone is sufficient to distinguish relatively pure magnetite samples.

Ilmenite, also known as Manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, fabrics, plastics, paper, sunscreen, food and cosmetics.

High intensity magnetic separators are used to upgrade iron ores contain- ing hematite or ilmenite. Dry separators require ore that is finely sized and bone dry. Get Price

Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides.It is the oldest known iron oxide mineral that has ever formed on earth, 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 ...

As another difference between magnetite and hematite, hematite is a component of rust, but magnetite is not. Moreover, when considering the magnetic properties of the two minerals, magnetite is a naturally strong magnet, but in hematite, magnetism occurs upon heating.

Ilmenite. Ilmenite is a dense, black metallic mineral that can be confused with metallic hematite, but again the two mineral’s streak should serve to distinguish them. Ilmenite exhibits a black streak similar to that of magnetite, while hematite’s streak is red to reddish brown. Graphite.
