iron ore hematite magnetite limonite
In the Earths crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.

Magnetic separation of hematite and limonite …
01.06.2002 · From the experimental results, the present work has shown that the magnetic separation of hematite and limonite fines from iron ores can be considerably improved by selectively aggregating the fines through the hydrophobic flocculation induced by sodium oleate, kerosene and a sufficient kinetic energy input. The improvement might be attributed to the great increase of magnetic force on the iron mineral fines in a magnetic …
