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.

May 12, 2015· About 90% of the world's phosphate consumption goes directly into the fertilizer industry,1 which is typically accomplished through conversion of the raw phosphate rock to phosphoric acid. Industrial phosphoric acid production makes use of the "wet process", which consists of two steps: (1) sulfuric acid


compounds. They obtain energy for this process by metabolizing stored polyphosphate reserves and thereby release phosphorus during this phase at a rate of 0.4 to 0.5 milligrams of phosphorus for every milligram of acetate consumed. The result is a net increase in the amount of dissolved phosphate across the anaerobic phase of the process.
