Abstract
Recently, the Bureau of Mines developed a dewatering technique for phosphatic clay waste. The technique consists of treating the clay waste with a flocculant such as polyethylene oxide and dewatering the resulting flocs on a mechanical device such as a rotary screen. In small-scale continuous tests at the Bureau's Tuscaloosa Research Center, clay waste was consolidated from a nominal 4 pct solids to about 20 pct solids. Based upon these encouraging results, a field test unit was operated at the Estech Corp.'s City Silver Mine, located near Bartow, Florida. The unit is now operating at the occidental Suwannee River Mine near White Springs, Florida. This report describes the results of field tests conducted to date.
