Abstract
The paper presents the results of leaching of low-grade copper sulfide ore with average Cu content of 0.33% and an oxide content of about 7%. The experiments were carried out in sulfuric acid solution and with the addition of Fe(III) ions that had the role of oxidant. During the leaching period of 23 days, with sulfuric acid, the concentration of copper in the solution ranged from 0.05 to 0.230 g/dm3, and iron from 0.125 to 0.350 g/dm3. With the addition of Fe(III) ions to the process, the concentration of copper in the solution moved in the same range. These results show that a longer period is needed for the oxidation and dissolution of this raw material.
