Heterogeneous reaction of NO2 with hematite, goethite and ...

The iron fractional solubility for unreacted hematite, magnetite and goethite were found to be approximately in the range of (1-10) × 10 −5. After heterogeneous reaction with 2.5 ± 0.1 ppmv NO 2 for 24 h, the increase in iron fractional solubilities was very small and in some cases even insignificant.

Types of Iron Ore: Hematite vs. Magnetite | INN

Did you know that there are different types of iron ore? Iron is most often found in hematite and magnetite ores, though goethite, limonite and siderite ores are also common sources.

Influence of 25% Goethite on the Surface Chemistry of Hematite

Surface stone 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 ...
