Abstract

In order to study the effect of mechanical activation on the sulphuric acid leaching of CuFeS₂, four samples were milled using an Atritor mill during 1, 5, 8, and 15 h. The powders were microstructural and morphologically characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The samples were leached using a solution of H₂SO₄ (0.54 M) at 298 K. The Cu⁺² concentration was determined by means of atomic absorption spectrophotometry. The results obtained indicated that the increase in milling time results in increased recovery of Cu. The maximum recovery of Cu was 38.2 % for a milling time of 15 h.
