Nitrophosphate process Wikipedia

The nitrophosphate process (also known as the Odda process) was a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927.. The process involves acidifying phosphate rock with nitric acid to produce a mixture of phosphoric acid and calcium nitrate.. Ca 3 (PO 4) 2 + 6 HNO 3 + 12 H 2 O → 2 H 3 PO 4 + 3 Ca(NO 3) 2

EuroChem's nitrophosphate route to produce zero-waste

Complex mineral fertilisers can be produced via various processes or production routes. An important production step is the conversion of the phosphor from the natural rock phosphate into a plant available form. One of the possible processes to do so is called the nitrophosphate route or Odda process.
