Phosphorus Fertilizer

Phosphate rock is either treated with a furnace (dry) or treated with a sulfuric, phosphoric, or nitric acid (wet) to produce phosphoric acid. The dry process is more expensive but produces very pure phosphoric acid. Triple super phosphate (TSP) is produced by the reaction of phosphate rock with phosphoric acid.
