Ilmenite is a dense, black metallic mineral that, when rubbed across a rough hard surface, exhibits a black streak similar to that of magnetite. As ilmenite is not magnetic, a magnet can be used to distinguish pure samples of the two. Some ilmenite samples appear weakly magnetic, however, due to inter-grown magnetite crystals.

Ilmenite exhibits a black streak similar to that of magnetite, while hematite's streak is red to reddish brown. Graphite. Graphite has a shiny metallic appearance and dark color so it may initially be confused with metallic hematite, but the two minerals' other properties easily distinguish them.

Magnetite Minerals; Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance. The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses.

— Magnetite and ilmenite make up nearly 60% of the rock in drill core through gabbroic rocks near Clam Lake in T.43N. R.4W. (Dugan and Ervin, 1977). CLARK COUNTY: Magnetite occurs with quartz in "thin discontinuous" iron formation found in scattered outcrops about …
Physical Properties of Ilmenite. Ilmenite is a black mineral with a submetallic to metallic luster. With just a glance it can easily be confused with hematite and magnetite. The differentiation is easy. Hematite has a red streak, while ilmenite has a black streak. Magnetite is strongly magnetic, while ilmenite is not magnetic.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

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.
Abstract The opaque minerals in ten lava flows of the Keweenawan series of Michigan were studied microscopically by the writer The basaltic lavas, which range in thickness from 100 to 1,400 feet, contain ilmenite, magnetite, hematite, intergrowths of magnetite-ilmenite and ilmenite-hematite, copper sulfides, native copper, and pyrite
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).

The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers. Ferric chloride and ferric sulphate are manufactured with magnetite as one of the starting materials. These chemicals are effective in clarifying raw water in water purification plants.
