Phosphate Fertilizer Plants

Phosphate fertilizers are produced by adding acid to ground or pulverized phosphate rock. If sulfuric acid is used, single or normal, phosphate (SSP) is produced, with a phosphorus content of 16–21% as phosphorous pentoxide (P 2 O 5). If phosphoric acid is used to acidulate the phosphate rock, triple phosphate (TSP) is the result. TSP has

Rock Dust Benefits Reduce Phosphorus fixation | RockDust ...

04/08/2012 · Rock Dust Benefits Reduce Phosphorus fixation. Farming trials have shown that when Phosphorous fertiliser is added to soil, more than half becomes fixed in the soil, leaving a much smaller amount for plant uptake. Adding Rock Dust allows much more Phosphorous to be available for plant uptake, and thus can largely reduce the amounts of ...

Phosphate Rock

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.
