Oct 03, 2018Abstract. Oil sands tailings are composed of charged clay colloidal solutions that are stabilized due to their double layer repulsions. Due to these repulsions, the microstructural arrangement of clay platelets in tailings is observed to be a stable house-of-cards like pattern with dominant edge-to-edge or edge-to-face attractions.

Substitution of Clay Content for P

quantitative, the clay content may be insufficient to explain the complexity of the P adsorption and desorption processes and can thus lead to errors when separating the soils in buffering classes for fertilizer recommendations. For example, although CHa-1 soil has a low clay content (Class IV - 190 g kg-1), it presented the greatest Fe OX content

Controlled Dispersion of Clays and Its Effects on Phosphate Clay

Phosphate clay wastes, as currently produced, leave montmorillonite clay in a highly dispersed and disintegrated form. Alternative processing, where the extent of swelling and self-disintegration of such clays is controlled or limited, may result in improved settling and consolidation behavior. In this study, a method to control montmorillonite dispersion, through preservation of clay tactoids

Electrokinetic dewatering of phosphatic clay settling areas:

May 01, 2011A mathematical model is presented for the electrokinetic dewatering of suspensions of phosphatic clays. The modeling approach couples a boundary-element 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

Recently, the Bureau of Mines 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.

Flocculation Dewatering of Florida Phosphatic Clay Wastes.

Part of the investigation was performed in a cooperative research project with 10 phosphate companies in Florida. The colloidal properties of the phosphatic clay suspensions, called slimes, make them difficult to dewater and dispose of without impoundment storage aboveground. The flocculation dewatering method was investigated in bench
