HEMATITE (Iron Oxide) Amethyst Galleries: Hematite
Hematite is a primary component of ordinary rust, but the porousity, softness, and flakyness of rust is likely due to goethite. The beautiful iridescent coating sometimes found on hematite is due to Turgite, still another "not really a" mineral composed of a mixture of hematite and goethite and sometimes described as being a hydrated hematite.

HistoryEdit. Iron prospector Henry Schneider arrived in Furness in 1839 and, with other investors, opened the Furness Railway in 1846 to transport iron ore and slate from local mines to the coast. In 1850 extensive hematite deposits were discovered of sufficient size to develop factories for smelting and exporting steel.

To help the environmental waste problems and reducing cost, hence the idea to convert mill scale from the steel industry waste into hematite (Fe 2 O 3) which is the most important element in producing NiZn ferrite. Successful conversion of the mill scale into hematite was proven by XRay Diffraction (XRD) analysis by designing and fabricating a magnetic separator.
