Abstract
Dewatering of mineral slurries is a complex process that is affected by many variables. The U.S. Bureau of Mines is presently investigating techniques to improve the dewatering of fine-particle slurries. This study examined the roles played by two widely used polymers, polyethylene oxide and nonionic polyacrylamide, in the dewatering of bentonite, kaolin, and attapulgite using a pressure filter and a trommel screen. This study also evaluated the cooper- eaton equation for use in predicting the compaction behavior of clay slurries during pressure filtration. The results showed that for pressure up to 40 psig, the cooper-eaton equation adequately represents compaction by pressure filtration. This study also showed that compaction is much more efficient in pressure filtration than in trommel dewatering.
