Types of Iron Ore Hematite vs. Magnetite Investing News

The difference is the level of impurities in magnetite deposits which are removed by magnetic seperation and then pelletising is needed to agglomerate the fine magnetite material.

Quantification of Al-goethite from diffuse reflectance

This study proposed that magnetic properties can be used to reach this goal because the magnetic properties of Al-goethite are dependent on the particle size, crystal defect and crystal parameters, which are controlled by Al substitution (Schulze 1984; Dekkers 1989; Liu et al. 2004, 2006). Thus, Al substitution can affect the magnetic properties of goethite.

Iron Ore Mining Artifacts

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or siderite. Hematite is also known as natural ore. The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces.
