| titleOfInvention | Fertilizer and crystalline potassium nitrate - by a single process from rock phosphate |
| abstract | Prepn. in a single process of high purity crystalline KNO3 and a chloride-free N:P:K fertiliser by treating the rock phosphate with a liquor contg. HNO3, H2SO4 and KHSO4 filtering off the CaSO4 and washing it with water, recycling the wash water to the prim. reaction vessel cooling the filtrate from the CaSO4 and crystallising out the KNO3, collecting and drying the KNO3, partially evapg. the filtrate from the CaSO4, treating the concentrate with NH3 to give a granulation slurry and granulating to give a fertiliser. |
