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,

2018-6-15  The total copper recovered from its ore through flotation process is about 56% [ 6, 18 ], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).
