Speciation and leachability of copper in mine tailings

2005-9-1  The copper speciation in tailings from porphyry copper mining is highly dependent on the particle size. This was found investigating tailing from El Teniente copper mine near Rancagua, Chile. In the smallest particles of the tailing the dominating species of copper are carbonates and oxides—around 70% of the solids.
