Reduction roasting of limonite ores: effect of

Sep 01, 2006Calcination of limonite ore was achieved by heating the ore for 20 min at 600 °C, or until insignificant change in its weight is observed as a result of dehydroxylation. Calcination was conducted in a muffle furnace. The calcined ore was kept in an oven at 105 °C to prevent the re-absorption of free moisture. 2.3. temperature reduction

Limonite Wikipedia

Limonite (/ ˈ l aɪ m ə n aɪ t /) 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) n H 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 magnetite, and
