The Bureau of Mines is developing a dewatering technique for coal- clay wastes. The technique consists of mixing coal-clay waste with the flocculant polyethylene oxide (peo) and dewatering the resulting flocs on a hydrosieve screen followed by further dewatering on a rotary trommel screen. Coal-clay waste slimes containing from 7 to 28 weight-percent solids have been consolidated up to 50 weight- percent solids using about 0.5 Lb of peo per ton of dry solids.
