ABSTRACT:
Oil shale mineral solids are separated from a fluid in a process comprising heating the mineral solids to at least the magnetic transformation temperature of a portion of the solids and thereafter magnetically separating mineral solids from the feed. High gradient magnetic separation techniques are preferred.
