The US Bureau of Mines is investigating a method of dewatering variety of fine-grained wastes, including coal-clay waste slurries. The method consists of mixing the waste slurry with a flocculant and dewatering the floc on static hydrosieve and/or rotary trommel screens. Laboratory tests on coal-clay waste slurries using polyethylene oxide were successful, and so small-scale continuous tests were carried out. Both series of tests are described. It was found that a static hydrosieve-type screen was sufficient to dewater the material to 50% solids. A large-scale field test unit is now being installed at a mine in Alabama.
