Discussions Mineral Collecting, Localities, Mineral

Feb 16, 2015 · Hello everyone, might someone please give this newcomer, in simple to understand terms, any tips on determining if a specimen is hematite or goethite. I appreciate that the two are related but I would just like to label my specimens correctly. I have recently visited a series of well known Cornish tin mining sites (St.

Hematite Wikipedia

Claysized hematite crystals can also occur as a secondary mineral formed by weathering processes in soil, and along with other iron oxides or oxyhydroxides such as goethite, is responsible for the red color of many tropical, ancient, or otherwise highly weathered soils.

Limonite Iron Ore Description, chemical formula and uses

Jan 28, 2014 · Limonite is another ore of iron, this time with a chemical formula of FeO(OH)·nH 2 O, although it can be rather variable in compositions so could have other formulas, and is not considered a true mineral because of the variability of structure and is a mixture of other minerals. A lot of what is considered Limonite is actually Geothite, an iron oxide which is the most common component of iron

On the goethite to hematite phase transformation

Abstract. This study deals with some microstructural and crystallographic aspects of the thermally induced transformation of goethite (αFeOOH) into hematite (αFe 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.

Transformation of various kinds of goethite into magnetite

The intensity of peaks corresponding to goethite especially 110, 111 and 130 decreased with aging time, while a progressive increase in main magnetite peaks was noted. After one week of reaction, goethite peaks were still present in the diffractogram (Fig. 1a) showing that transformation of goethite into magnetite was not fully achieved.
