Leaching And Kinetic Modeling Of Calcareous Bornite

Leaching and kinetic modeling of calcareous bornite in ammonia ammonium sulfate solution with sodium persulfate. The hydrometallurgical method has been more practically acceptable because there is no production of SO 2 gas. Bornite is often found in copperore bodies with other minerals such as chalcopyrite and chalcocite.
