Haematite: odstone Feature tandfonline

haematite with its polygonal structure has a submetallic to metallic lustre. These three categories, in the writer’s experience, also usefully serve as resistivity indicators for solid materials in the dry state. A succinct summary of haematite as a formal mineral can be found in Deer et al. (1992). Details of Australia’s commercial

Hematite an overview ScienceDirect Topics

Hematite. In the hematite process, zinc ferritebearing residue is dissolved by sulfur dioxide and acid and, after purification, iron is precipitated as Fe2O3 by injection of oxygen at 2MPa and 200°C. The process is expensive, and in 1999 only one such plant was operating. From: Encyclopedia of Materials: Science and Technology, 2001.
