Hematite - an overview | ScienceDirect Topics

Hematite is a representative metal oxide for visible light absorption [13–15]. It has a band gap of 1.9–2.2 eV, which covers most fractions of the visible light. Theoretically, based on this band gap energy, the maximum STC efficiency for hematite can reach 12.9% with a photocurrent of 10.5 mA/cm 2.

Understanding the effects of goethitic iron ore - Process ...

As demonstrated on the plot below, where the balance of ore textural components is shifting to the right with time from hematite-dominated (blue, red) to goethitic (brown, yellow), rising proportions of these ore types are resulting in increasingly goethitic iron ore products. This has had a noticeable impact on the iron ore supply chain.

Iron ore classification: Critical insights for resource ...

Mar 14, 2017 · A powerful iron ore classification system is a critical prerequisite. Without a sufficiently and appropriately characterised resource, modelling will be inaccurate reducing an organisations ability to implement cost reductions and productivity gains across the iron ore value chain.
