Best Iron Ore-Haemetite Or Magnetite
Magnetite
Limonite is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.Limonite is one of the three principal iron ores, the others being hematite and …
