After crushing oxide-type copper ores, such as azurite (2CuCO 3 · Cu(OH)3), brochantite (CuSO 4), chrysocolla (CuSiO 3 · 2H 2 O) and cuprite (Cu2O), dilute sulfuric acid is applied to the surface of the material on leaching pads or in leaching tanks. As the acid trickles through the ore, it combines with the copper, producing a weak copper sulfate solution.
