phosphate rock dewatering

Electrokinetic dewatering of a phosphate clay ScienceDirect The principles of electrokinetic dewatering are: (1) electrophoresis, the movement of colloidal particles in a direct current electric field; (2) dielectrophoresis, the movement of colloidal particles in a nonuniform electric field; and (3) electroosmosis, the water flow in porous media in a direct current electric field.

Electrokinetic Dewatering System that Effectively Removes ...

Continuous operation of this electrokinetic dewatering system removes water from phosphatic clay suspensions, thereby achieving clay cake solid contents approaching 25 percent more rapidly than other methods. In Central Florida, the quantity of clay settling ponds covers more than 150 square miles, taking up approximately 40 percent of the phosphate mining land mass. Drying these clay settling ...

Electrokinetic geocomposites (eGCPs) installed into the FFT disposal area may improve in situ dewatering, as eGCPs can drain water expulsed during FFT consolidation as well as impose a voltage across FFT to displace water by electroosmosis. This paper presents a laboratory device specifically developed to evaluate eGCP performance for sludge dewatering. Based on the oedometer principle, …
