ABSTRACT:
Oil shale mineral solids are separated from a fluid such as retorted shale oil by heating the mineral solids to a temperature above about 480.degree. C. and above the magnetic transformation temperature of at least a portion of the solids. The temperature of the solids is maintained above 480.degree. C. for no longer than about one minute, and the solids are magnetically separated. High gradient magnetic separation techniques are preferred.
