Beneficiation Plant Yield Calculation Copper Rock
Beneficiation The fast movement of the slurry causes it to bang against the pipes, and this breaks apart any clay balls. What arrives at the beneficiation plant are fine-grained sand, clay and phosphate sediments suspended in water. At the beneficiation plant, the slurry is first run through a screen, which filters out the coarser sand.

Phosphate Beneficiation
The beneficiation plant does this with equipment called "hydro-cyclones". Slurry from the washer is fed tangentially into the cyclone (a conical chamber) at a high G force. The slurry swirls around inside the cyclone until fines overflow the top of the chamber. Coarse sand and phosphate particles swirl to the bottom of the cyclone and exit.
