Bureau of Mines Technology for Dewatering of Phosphatic Clays.
Paper in Phosphatic Clay Workshop Florida Inst Phosphate Res 1982 (02-020-012) :55-64
The Bureau of Mines has 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 wt % solids to about 20 wt % solids. Based upon these results, a field test unit was operated at the Estech Corp. Silver City Mine, located near Bartow, Florida. The unit is now operating at the occidental Suwannee River Mine located near White Springs, Florida. This report describes the results of field tests conducted to date.
