| Abstract: | For a sort of copper oxide with high content of clay, by doing permeability experiments with washing ore grainsof different sizes, it is proved that ore grains within the range of ＋2 - -25 mm are of better permeability. This ore particlesize is thus decided as test condition of column leaching. With the sulfuric acid concentration being 60 g/L, liquid-solidratio 2∶1, leaching-stop ratio 2∶1, leaching time 50 d, liquid fabric strength 30.0 L/（m^2·h）, Fe leaching rate is about1.6%, per-ton copper sulphate consumption is about 14 t, and copper leaching rate is about 56%. |
