The ball mill 5 receives phosphate rock supplied from a wet phosphate rock feed silo 7, which in turn is fed from a phosphate rock pile 6. The ball mill is operated to grind the phosphate rock. The ground rock is fed to a cyclone separator 4 and two fractions are separated.
The inputs required to produce one ton of DAP fertilizer are approximately 1.5 to 2 tons of phosphate rock, 0.4 tons of sulfur (S) to dissolve the rock, and 0.2 tons of ammonia. Changes in the supply or price of any of these inputs will impact DAP prices and availability. The high nutrient content of DAP helps reduce handling, freight and ...

As late as the 1960s phosphate rock mining contributed about ten percent of the total value of Tennessee mineral production. Beginning in the 1970s, the number of operations dropped significantly, and by the 1980s only two were left. In 1991 both operators announced closings, ending phosphate mining and refining in Tennessee.
