May 10, 2016 · After the calcination process, an enrichment of 3.1–3.4% of the Fe grade was observed because of the thermal decomposition of goethite to hematite, which involves the loss goethite's hydroxyl group. The sinter samples exhibited an average Fe grade of 59.1%. The main mineral phases in the iron ore sample were goethite and hematite.

Hematite: A primary ore of iron and a pigment mineral

Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
