As a part of research conducted in its mission to effect pollution abatement, the Bureau of Mines, U.S. Department of the Interior, is developing a dewatering technique that allows for disposal of mineral wastes, for reuse of water now lost with these wastes, and for reclamation of mined land. The technique utilizes a high-molecular-weight nonionic polyethylene oxide polymer (PEO) that has the ability to flocculate and dewater materials containing clay wastes. A variety of different clay wastes have been successfully dewatered in laboratory experiments. Coal-clay waste was consolidated from 4 to 57 weight-percent; potash-clay brine waste from 20 to 62 weight-percent; phosphatic clay waste from 16 to 49 weight-percent; uranium mill tailings from 15 to 67 weight-percent; talc tailings from 10 to 53 weight-percent. The consolidated materials can be handled by mechanical devices such as trucks and conveyors for disposal in mined-out areas.
