Beneficiation of phosphate rock differs greatly from one deposit to the next, with common methods including screening, grinding, flotation, classification, filtration, and more. In general, however, they are all processed via a wet process, resulting in a wet phosphate rock, which must be dried before it can move on to subsequent processing.

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% solids slurry. Since that time, most U.S. installations have converted to wet …
