Caliche ore, the history of Chilean nitrate

In agriculture, potassium nitrate is used as a soluble fertilizer and is a source of nitric nitrogen and potassium, which is virtually free of chloride. Potassium nitrate is an ideal source of N and K for optimal plant growth and contributes to the health and performance of crops.

Potassium nitrate is obtained through a process that mixes sodium nitrate, derived from Caliche and potassium chloride, obtained from the brines from Salar de Atacama, in northern Chile. This process uses solutions rich in sodium nitrate to which potassium chloride is added, producing the reaction to obtain potassium nitrate.

Caliche ore, the history of Chilean nitrate

Caliche is a mineral that contains high concentrations of nitrate and iodine, and, to a lesser Extent, potassium. Caliche is encountered in layers or veins which are from 20 cm up to 5 meters thick, covered by a shallow, sterile surface layer that can be from half a meter up to 1.5 meters thick. Uses for caliche have been known for a long time by the native peoples, and during the Spanish conquest in the 17th century it was used as an agricultural fertilizer. Caliche stems from the Quechua word “cachi”, meaning salt.
