Surface chemical techniques were used in an attempt to characterise two samples of hematite from the Iron Duke deposit in the Middleback Ranges of South Australia. The surface chemistry of the two naturally occurring samples was compared to a high purity, synthetic sample. The presence of 25% goethite affected the isoelectric point of the hematite, but the zero points of charge for all the ...

Goethite often forms through the weathering of other ironrich minerals, and thus is a common component of soils, concentrated in laterite soils. The formation of goethite is marked by the oxidation state change of Fe 2+ (ferrous) to Fe 3+ (ferric), which allows for goethite to exist at surface conditions. Because of this oxidation state change, goethite is commonly seen as a pseudomorph.
