The objective of this research is to study the acid-nitrate-chloride system in the chalcopyrite leaching process (CuFeS2) in order to propose a hydrometallurgical process that allows the use of salts or discarding solutions from the caliche industry as well as saline discard solutions (such as the rejection solution of the reverse osmosis process) or raw seawater. The methodology used involves conditioning and leaching low grade ore, concentrate, and pure chalcopyrite samples by stirring while varying concentrations of chloride, solvent, source of nitrate and pretreatment. The system has shown good copper extraction results at atmospheric pressure, achieving over 60% and up to 90%. Salts and discard solutions have been demonstrated as alternatives to raw materials in the process. Additionally, a conditioning stage is essential to accelerate the dissolution kinetics of copper in the studied systems.
