ABSTRACT:
A method and composition are provided for transporting coarse particles of coal in a dense liquid CO.sub.2 media. The dense media contains fine particles of densifying material such as coal or magnetite which form a suspension in the liquid CO.sub.2. The suspension is capable of supporting large particles of coal for transportation in a liquid CO.sub.2 slurry pipeline. Use of the dense media allows the pumping of the coarse coal particles at slower velocities than if the fine densifying particles were not present.
