Abstract
In a transportation of solid materials of a wide grain-size distribution, including fine and coarse particles, a liquid as a transportation medium is added to the materials to turn them into slurry, so as to transport the latter hydraulically. The waste solution after the transportation is thickened into a heavy media, by dehydrator and solid-liquid clarifier, and reserved in a heavy media tank adapted to suitably adjust the concentration of the media. The media in the heavy media tank is returned to the transportation source, so as to serve as the transportation medium for transporting the slurry.
