Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate).
The Bureau of Mines, US Department of the Interior, conducted studies to recover phosphate from four dolomitic southern Florida deposits not currently mined. The samples contained 5.8–10.2 P2O5 and 1.7–4.8 MgO. Chemical analyses of sized fractions indicated that no pebble concentrate, +1.2 mm (+ 14 mesh) could be produced from these samples. A scheme was developed that consisted of.
