Abstract
A technique was devised by the Bureau of Mines to recover coarse (plus 1.2 Mm) 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 17.0-Pct-p2o5 reject to 24.5 pct p2o5, with a phosphate recovery of 63 pct.
