goethite (mineral) — Encyclopedia Britannica Goethite varies in colour from yellow-brown to red. It is composed of about 80 to 90 percent Fe 2O 3 and approximately 10 percent water.

PHASE TRANSFORMATIONS FROM GOETHITE TO HEMATITE AND THERMAL DECOMPOSITION IN VARIOUS NICKELIFEROUS LATERITE ORES B. Rizov Faculty of Technology and Metallurgy, University Ss Cyril and Methodius in Skopje, Rugjer Boskovic 16, 1000 Skopje, R.Macedonia

Abstract. Synthetic pigments of goethite (Bayferrox R) of different particle size were investigated by DTA, IR, DSC, TG and X-ray diffraction measurements.It follows that a so-called 'hydrohematite' described in the literature does not exist as a discrete intermediate during the dehydration course from goethite to hematite.

Abstract. This study deals with some microstructural and crystallographic aspects of the thermally induced transformation of goethite (α-FeOOH) into hematite (α-Fe 2 O 3), occurring at about 300 °C.Powder specimens of goethite have been annealed in air at different temperatures, ranging from 200 °C up to 1,000 °C.

The temperature induced goethite-hematite phase transformation that occurs at about 250 °C was studied using in situ synchrotron X-ray powder diffraction with a capillary Debye-Scherrer geometry and a translating image plate system (TIPS).

During the beneficiation of these low grade hematite iron ores, vitreous goethite comes with hematite and partly ocherous goethite along with kaolinite and gibbsite which contribute to the loss on ignition (LOI) in iron ore concentrate.

Therefore, the dehydroxylation of goe- thite would create hematite at the temperature range 400 ?C to 500 ?C. Kaolinite and goethite could not be found at temperature above 600 ?C.
