Hematite, heavy and relatively hard oxide mineral, ferric oxide, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for 'blood,' in allusion to its red color. Learn more about hematite in this article.

Siderite is both an iron ore and gangue mineral. Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous. It is part of a large group of isomorphous minerals, the calcite group carbonates, which share similar physical properties, and rhombohedral crystal form.
