Process for the dewatering of phosphate slimes

摘要

The process for electro-sedimentation, dewatering and consolidation of Florida phosphate slime by the process of placing an anode at the bottom of a holding facility for the storage of the phosphate slime; filling the holding facility with phosphate slime; placing a cathode on the surface of the solid portion of the phosphate slime but below the surface of any supernatant liquid; applying an electrical current to the cathode to produce a separation of the phosphate clays from the phosphate slime and draining off any decanted water to produce phosphate slimes with a solid content of at least about 15 percent.
