How are nitrates produced?
Nitrate is mined from natural deposits of caliche ore . These deposits are mined primarily from saline mineral deposits that form veins and irregular masses in the bedrock. The ore is extracted by first drilling or blasting the soil overburden covering the deposits, then transported to the extraction plant. The overburden, usually 1 to 2 m thick, is removed mechanically and left on-site (Collings 1950). During refinement, crushed ore is dissolved at 35°C to extract nitrates, sulfates, potassium, and iodine. Nitrate precipitates are removed, crystallized, dried, and prilled.
