Thermodynamics of Reactions during Nitric Acid Leaching of Minerals of a Copper Concentrate

摘要

Conditions for the effective dissolution of sulfides without the isolation of elemental sulfur and iron oxides are determined at 20 and 100°C using "potential-pH" thermodynamic diagrams in the Cu-Fe- S-N-O-H system. The acquired thermodynamic characteristics of leaching of the copper concentrate with nitric acid can be used when selecting the production parameters for processing the copper concentrates.
