    Producing one ton of phosphate rock creates one ton of phosphatic clay by-product. The Florida phosphate industry generates approximately 100,000 tons of phosphatic clay each day El-Shall 2009. This clay is returned to the landscape, where it can be contained. Phosphatic clay is highly plastic, or moldable, and retains large quantities of ...

  • A Constitutive Relationship For Electrokinetic Dewatering

    Benchtop experiments were performed, in which an electric field was used to enhance separation of water from phosphatic clay suspensions from a central Florida mine. A constitutive relationship was established that relates the increase in solids content to operating time and the applied electric field. An upper limit to the degree of separation was found to be a function of electric field, and ...

    Bentonite clay is one of the abundant clay minerals at the earths surface, which can be used as an effective adsorbent for many toxic substances in soil, water and air. Natural Bentonite is effective adsorbent for cations but it shows lower affinity towards negative groups, like phosphate, due to the absence of reactive adsorption sites for ...

    The Bureau of Mines has 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. In small-scale continuous tests at the Bureaus Tuscaloosa Research Center, clay waste was consolidated from a nominal 4 wt solids to a
