Abstract
Coal-clay waste slurries were dewatered in laboratory- and small- scale continuous tests by the Bureau of Mines using polyethylene oxide (peo) as a flocculant. Dewatering from a nominal 7-wt-pct solids to over 50-wt-pct solids was accomplished using 0.5 Lb of peo per ton of feed in small-scale continuous tests. Parameters such as ph, initial solids content, and peo concentrations were investigated. Water recovered from dewatering was reused as dilutant for peo solutions.
