Research output: Contribution to journalArticlepeer-review


Reaction rates for copper dissolution have been known to be affected by liquid phase mass transfer. As all rate equations contain a mobility term and a driving force, it is important to know the equilibrium condition of the reaction to fully determine the reaction rate kinetics. The paper aims to study the dissolution equilibrium of copper in contact with an FeS-Na2S matte. The equilibrium Cu2S content in the matte was determined at temperatures ranging from 830 °C to 1050 °C.
