Limonite - Wikipedia

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)nH2O, 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 has been mined for the production of iron since at least 2500 BCE.

Thermal characteristic of limonite ore upon calcination ...

May 01, 2018  Thermal characteristics of the limonite laterite ore types have been studied using TG / DTA. There are four endothermic peaks at 250, 646, 900, and 1023 °C with a total mass loss of 10.07wt%. These four peaks correspond to the XRD results on samples calcined at 600-1000 °C. Analysis of TG / DTA to the mixture of limonite and graphite showed two endothermic reaction peaks
