Phosphatic Clay Dewatering

The process for electrosedimentation, 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 hode on the surface of the solid portion of the phosphate slime but below the surface of any supernatant liquid; applying an ...

The discarded phosphatic clays from mining operations have historically been stored behind earthen dams for long periods of time before any reclamation was accomplished. In efforts to expedite the dewatering and reclamation of the clay ponds, the phosphate industry explored alternatives to conventional clay disposal practices. One alternative, employed by CF Industries, Inc., combines the clay ...

Dewatering method and agent Florida Institute of . Nov 16, 1993 · More effective dewatering methods are described in the Bureau of Mines Reports of Investigations,, Investigation Nos. 8611 (LargeScale Dewatering of Phosphatic Clay Waste from Central Florida), 8349 (Flocculation Dewatering of Florida Phosphatic Clay Wastes), and others.

Phosphatic clay minerals form naturally and are stable across a wide range of geologic conditions Ma (1996). Phosphatic clay has been used primarily in association with remediation Pbcontaminated soils (Ma et al.(1995), singh et al.(2001), seaman et al.(2001) and Ryan et al.(2001). Therefore, the objectives of the current study are to: 1 Investigate the effectiveness of phosphatic clay in ...

 · A mathematical model is presented for the electrokinetic dewatering of suspensions of phosphatic clays. The modeling approach couples a boundaryelement model for solution of Laplace's equation to a recently developed constitutive equation that relates the change in solids content with applied electric field and time. The observation that the electric field controls both the maximum solids ...

 · Phosphatic clay is a byproduct of phosphate strip mining, particularly in Florida, USA. This waste material occupies about 100 000 acres of land which could be utilized for other causes. Thus, its use as an alternating cementing material for the addition into the mixing matrix of cement paste and concrete to yield higher strength would be profitable for both materials involved.
