Barite orebodies and occurrences are almost as varied as the number of occurrences. As in most mining situations, the design of a mine plan and implementation of a proper exploitation program must be approached on a case by case basis. Proper and sufficient geologic control of a barite orebody must precede the development of a mine plan.

Therefore, hematite can be separated from barite using high-intensity magnetic separation methods, which use magnetic fields with intensity ranging from 0.02 to 4.0 Tesla [32, 33]. The separation of hematite particles can be enhanced to about 82% by reducing the particle size of the barite ore below 63 µm [34] .
