The Production Process Story | Yara International

Phosphate mining. In the nitrophosphate process used by Yara, nitric acid is used for digestion of the phosphate rock. This benefits the extraction of calcium by crystallization as calcium nitrate (CN), and processing of high-quality prilled or granular CN products. The majority of manufacturing processes for complex fertilizers.

Calcium nitrate - Wikipedia

Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter), is an inorganic compound with the formula Ca(NO3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Nitrocalcite is the name for a mineral.
