RECOVERY OF COPPER FROM COPPER SLAG AND

2014-9-8  Based on the chemical compositions of the slag and the slag flotation tailings (Table 1), it can be concluded that the copper dissolved from the slag flotation tailings mainly originates from the copper oxide phases (about 10 wt.%), which are not amenable to flotation. Low copper extractions both from the slag and the slag flotation tailings indicate that sulphuric acid is not a suitable reagent for leaching these materials, at room temperature. This conclusion is in line with the study by Banza et al. (2002) where the leaching of copper smelter slag with sulphuric acid (500 kg/Mg slag) resulted in copper and iron extractions of 20% and 52%, respectively, at 20oC, whereas the maximum copper and iron extractions were 60% and 90%, respectively, at 90oC. Also, based on the results depicted in Figure 2 and 3, it can be concluded that the iron minerals are dissolved more easily in sulphuric acid than the copper minerals, both from the slag and the slag flotation tailings,

As shown in Figure 4, an increase in PAX concentration lead to drastic increases in the grade and recovery of copper, whereas further increases in PAX had mod-erate changes in the grade and recovery of nickel. The grade and recovery of nickel increased up to 0.41 wt% and 31.0% from 0.17 wt% and 10% with in-creasing PAX dosage from 0 to 75 g/t. A further increase in PAX took place a gradual decrease in the grade and recovery of nickel. Results showed that the maximum recoveries of Cu and Ni were achieved at 87.80% and 29.77% when PAX dosage was 100 g/t and 75 g/t, respectively. But a larger amount of collector would cause to float
