Paradas method

From Wikipedia, the free encyclopedia

The paradas method (Spanish: método de paradas, sistema de paradas) was a process to extract nitrate from caliche by leaching. In this method caliche was boiled in water in large pans called "paradas".[1] It was a firewood and labour-intensive process,[2] and it required the frequent relocation of the mining camps.[3] The paradas method was phased out in the 1850s by a new system invented by Pedro Gamboni which required less fuel and labour.[2]

The paradas method led to a massive deforestation of Pampa del Tamarugal around La Tirana and Canchones and some areas to the south of these localities.[4]
