The mining and refining of nitrates was a dangerous enterprise which cost the lives of many miners. The high wages and relatively low cost of living at the mines, however, attracted large numbers of laborers, many of whom regarded working in the nitrate pampa as an opportunity to amass enough capital to start their own businesses in the south.

GHOSTS OF THE ATACAMA: THE ABANDONMENT
Apr 03, 2013Nitrate Mining and Production The earliest method of nitrate mining in Tarapacá involved digging or drilling holes in the desert floor to determine the extent of the nitrate bed to be mined. Maps would be drawn depicting the likely nitrate distribution and a series of blast-holes dug into these areas.

Pinning down nitrate sources in mine water Mining Review
Nov 28, 2017Skinner’s presentation advances tools for mines to more efficiently identify nitrate sources in surface and ground water. Mining can result in increased nitrogen levels in groundwater through the use of nitrogen-based explosives. Most commercial explosives contain between 70% and 90% ammonium nitrate which is highly soluble.

Saltpeter mining ScienceDirect
Jan 01, 2019The mining and processing of cave nitrate-enriched sediments is a relatively simple endeavor, although labor intensive. The tendency of these sediments to contain a suite of nitrates rather than just potassium nitrate is one reason the archaic spelling saltpeter is used in reference to the mining of cave nitrates and the caves in which they occur.

Lead Nitrate Lead nitrate is added to the leach circuit and has the effect of accelerating the gold dissolution rate. Slurry Density Reagent consumption is minimised by maximising slurry density, since optimal concentrations can be achieved at lower dosages, due to the smaller volume of solution per unit mass of material.
