Saltpeter Mine Ruins in Mammoth Cave. The process involved burial of excrements (human or animal) in the fields prepared for that purpose beside the nitraries, watering them and waiting until the leaching process did its job; after a certain time, operators gathered the saltpeter that "came out" to the ground surface by efflorescence.
New technological advances in the mid-1800s transformed the saltpeter process. Tanks that were used as part of the saltpeter production process. Michael Runkel/robertharding/Getty Images.
In 1913 Santa Laura halted its production until the Shanks extraction process was introduced, which enhanced productivity. However the economic model collapsed during the Great Depression of 1929 because of the development of the synthesis of ammonia by the Germans Fritz Haber and Carl Bosch , which led to the industrial production of fertilizers.
The process involved burial of excrements (human or animal) in a field beside the nitraries, watering them and waiting until leaching allowed saltpeter to migrate to the surface by efflorescence. Operators then gathered the resulting powder and transported it to be concentrated by ebullition in the boiler plant.
Developed for the extraction of saltpeter, it is a Chilean National Monument and part of a UNESCO World Heritage Site designated as Humberstone and Santa Laura Saltpeter Works. [ 1 ] [ 2 ] [ 3 ] History

The commencement of the export of nitrates to the Europe and the US in the 1830s marked the most important milestone in the history of the nitrate industry and brought consequences for the economies of the three countries sharing the Atacama ...
