  • Radioactivity and Phosphatic Clay Ponds

    When the pond settles the soil has higher levels of radioactivity than normal soil. The average Florida soil has about 2 pCi/g of radioactivity from both uranium and radium. A mineralized soil in an unmined area has about 10 pCi/g of radioactivity. A clay settling area has up to 40 pCi/g of radioactivity.

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity

    A settling pond's large surface area permits oxygen from the atmosphere to dissolve into the polluted water. The oxygen reacts with ferrous iron to form ferric ions, which quickly become yellowboy and settle. If mine water is alkaline and only contains iron, settling ponds may be the only treatment necessary.

    Tailings ponds are massive earth structures used to store coarse and fine solids contained in the oil sands deposit and recover water back to the main processing plant. These ponds are temporary storage facilities and need to be reclaimed when no longer in use.Fine solids from tailings streams tend to trap large volumes of water, making pond reclamation challenging at best.
