Hematite - an overview | ScienceDirect Topics

Iron Oxides—Fe 2 O 3. Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.
