    Jun 30, 2009  In the industrial practice of recovering boron from rich deposits in Turkey, the low grade fraction (typically finer than 3 mm) is discharged to tailings pond in order to produce a high grade concentrate (e.g., >40% B 2 O 3) as a feed to boric acid plants. The current study examines the recoverability of boron values from the tailing pond.

    Surface stacking is the disposal of tailings on the surface of the ground. As a non-settling, non-segregating suspension of solids, minimal water is released into the impoundment and the stacked tailings dries significantly faster than conventional ponds where fines (slimes) segregate and can seal the surface of the deposit, preventing drying.
