Fertilizer Focus Casale’s granulation process for NPK production is described below. It is based on phosphoric acid and potassium chloride as raw materials for P and K respectively, while the N source used can be ammonia with either ammonium nitrate or urea. General concepts The NPK process uses the phosphoric acid route. The main advantages are

To produce a phosphorus fertilizer, the rock is treated with acid; sulfuric, phosphoric or nitric. Each method has its advantages and constraints. The sulfuric acid route produces a low phosphorus fertilizer – single superphosphate - which is half gypsum. The use of phosphoric acid produces a higher concentration phosphorus fertilizer
