Speciation and leachability of copper in mine tailings

The influence of particle size on leachability of monosize chalcopyrite particles, 12 and 47 m, was investigated and it was found that the rate of copper leaching increases significantly by decreasing particle size (Wadsworth, 1979). However, the actual extent of this behaviour for different ores mixtures at different particles size classes varies
