Flotation studies of phosphate-bearing waste pond materials, low- grade washer products, and raw ores, all from the Tennessee Brown Phosphate District, showed that these types of materials could be treated without desliming to recover high-grade phosphate concentrates. The investigation showed that fine grinding before flotation was a requisite for increased recovery of the phosphate values, and that the optimum ph conditions were in the range of 10.0 to 10.5 When using anionic collectors. Multiple-cleaning of the rougher phosphate concentrate was required to produce high-grade concentrates. Phosphate recoveries ranged from 60 to 82 percent and were inversely related to the grade of concentrate produced.
