FAQ
Frequently Asked Questions
Not exactly. 'Saltpetre' often refers to potassium nitrate (KNO₃). 'Chile saltpetre' specifically refers to sodium nitrate (NaNO₃) mined from natural deposits in Chile.
It was primarily used as a nitrogen-rich fertiliser, in food preservation (especially for curing meats), and historically in the production of gunpowder and explosives.
Because the largest and most commercially significant natural deposits were mined in the Atacama Desert, which was contested by Chile, Bolivia, and Peru in the 19th century.
Its use declined drastically in the early 20th century after the Haber-Bosch process allowed for the synthetic production of ammonia and nitrates. It has very limited specialised use today.
