Rock grinding. Until 1973, most phosphate was ground dry in roller or ball mills. In that year, Agrico, at South Pierce, Florida, converted one of its dry mills to wet slurry grinding and proved that the plant water balance could manage the rock at a 65–68 percent solids slurry. Since that time, most U.S. installations have converted to wet ...

11.21 Phosphate Rock Processing 11.21.1 Process Description1-5. The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding. The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475.
Other benefits to the direct use of rock phosphate are: 1. It is relatively cheap compared to inorganic/chemical phosphorus fertilizers. 2. It is environmentally friendly. As a natural source of phosphorus, it avoids the use of inorganic fertilizers which contribute to green house gas emission during its manufacturing process. 3.
