RECOVERY OF COPPER FROM COPPER SLAG AND COPPER

obtained has been rather low (about 40%). Previous research indicated that such a low recovery was due to the presence of copper oxides in the slag, as well as to the fact that copper sulphides were predominantly found in particle size fractions below 38 µm. Accordingly, the objective of the present work was to investigate whether implementation of the hydrometallurgical processing of the slag or the slag flotation tailings could result in an increase in copper recovery.
