| Abstract: | 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. |
