Abstract

This work contributes to the thermochemical modelling of nitrate brines to estimate solute concentrations from ionic conductivity and temperature measurements. This indirect determination would allow significant savings in time and monetary costs related to the use of analytical laboratories for saline waters, so it could help to monitor and improve the controls of industrial operations and processes associated with the production of natural saltpeter, dissolution of nitrate fertilizers, leaching operations for ores and concentrates using nitrates, or in water treatments for nitrate residue solutions.
