Hematite is an iron oxide mineral with the ideal formula Fe2O3 and is one of the world’s principal iron ore minerals. It occurs in numerous geological environments and is especially important in iron formations and deposits enriched through alteration or weathering. High-grade hematite ores have historically been particularly valuable because of their high iron content and comparatively straightforward beneficiation.
These elements are often found is this element in the following Deposit Types:
Deposit Type: Banded Iron Formation (BIF) / Superior-type Iron Formation - Large Precambrian iron formations composed of alternating iron-rich and silica-rich layers.
Hematite is one of the principal iron minerals in oxide-facies Superior-type banded iron formations.
