Mined land reclamation by the Florida phosphate industry

During hydraulic processing of phosphate matrix enormous amounts of phosphate slimes are produced. Significant portions of mined land are utilized to store the slimes. Some dewatering of the slimes is essential before any reclamation of the storage ponds can be undertaken. Dewatering and reclamation of slimes storage ponds pose many problems which are not encountered in reclamation of other mined areas.
