Origin of Material
Sourced from the Critical Zone’s, Chromite layers in the Bushveld Igneous Complex, within UG2.
Approximate Mineral and Chemical Composition
Chromium Oxide (Cr2O3): This is the primary component of chromite, constituting a significant portion of its chemical makeup. Iron Oxide (FeO): Iron is commonly present in chromite, often in varying amounts. Iron oxide contributes to the overall composition and properties of the chromite mineral. Aluminum Oxide (Al2O3): Aluminum may also be present in trace amounts in chromite.
