The Bureau of Mines investigated a technique for dewatering clay waste consisting of flocculation with polyethylene oxide followed by screening of the resulting flocs. Results of laboratory tests as well as the results of small-scale and large-scale field tests are described in this paper. The procedure has been applied to clay wastes from phosphate, coal, bentonite, and potash operations and to the tailings from uranium, talc, copper, gold, silica, and mica mining operations.
