Rui Nunes Goethite from Cercal mines. Goethite is an iron bearing oxide mineral that often forms through the weathering of other iron-rich minerals, and thus is a common component of soils. The formation of goethite is marked from the state of change of Fe2+ to Fe3+, which allows for goethite to exist at surface conditions. Read More

Histoire de la pierre goethite. La goethite est un minéral pseudomorphe d'hydroxyde de fer qui se cristallise sous forme de masses, de botryoïdes, de stalactites et, rarement, de petits cristaux prismatiques. Cette gemme a été découverte par le minéralogiste Johann Georg Lenz en 1806 à Herdorf, en Allemagne. Il l'a nommé d'après le poète et philosophe allemand populaire de l ...

The goethite process precipitates crystalline aFeO-OH (goethite) as well as PFeO-OH, aFe202, and amorphous phases. The reaction is carried out at 90°C and pH 3.0, for 4—6 h in either batch or continuous fashion, and the iron (III) ion must be kept <1 g/L. Both jarosite and goethite soHds are usually lagooned.

Microwave-assisted magnetizing roasts were used to produce an iron ore product from low-grade, goethite-dominant, iron ore plant rejects. Goethite was found to be converted to hematite at temperatures above 370 °C on reduction in a microwave furnace under gas mixtures of 30:70 and 40:60 CO/CO 2. Reduction to magnetite occurred at higher ...
The amendment of AMF and goethite to soil increased the amount of rhizo-C accumulated in the >2 mm aggregate size class (Fig. 2a).More C accumulation was found in macroaggregates under AMF + goethite (Fig. 2a).In contrast, the rhizo-C in the 2–0.25 mm aggregate size was the highest under the control (0.32 g kg −1 of soil), and the other three …

From goethite to hematite: thermoanalytical aspects. The DTA curves in Fig. 1 display, as more intense endothermic peaks, those pertaining to the phase transition from goethite to hematite, occurring during the first heating run of the two goethite materials (SA and GS). This irreversible transformation occurs, as expected [3, 6, 7, 11–14], over a temperature range …

La goethite est un minerai de fer important, souvent prédominant dans les parties superficielle des gisements. La goethite des chapeaux de fer est cependant peu appréciée comme minerai à cause de la présence fréquente et pénalisante d'autres métaux. Dans les ocres, elle joue un rôle important de pigment.
