• Description:
  A technique was devised by the US Bureau of Mines to recover coarse [ + 1.2-mm (14-mesh)] North Carolina phosphate now discarded as waste. Concentration utilizes the difference in particle sphericity between the relatively flat calcite and the rounded phosphate pebbles. Sizing, treatment in a continuous hydraulic classification system, and grinding upgraded a 17% P2O5 reject to 24.5% P2O5 with a phosphate recovery of 63%. The CaO:P2O5 ratio was reduced from 2.49 to 1.66. [Description provided by NIOSH]
