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 phos-phoric acid is used to acidulate the phosphate rock, triple phosphate (TSP) is the result. TSP has
