dc.description.abstractThis paper describes the effect of acid leaching on the hydrodynamic properties of agglomerated copper tailings. Both the suction and the hydraulic conductivity curves were obtained before and after acid application in laboratory columns under unsaturated flow conditions. Using a classical approach originally developed for water and soil, we determined whether the post-acid application characteristic curves could be obtained from the pre-acid application ones. Results showed that acid modified the hydrodynamic properties of agglomerated tailings. Both the macropore volume and the saturated hydraulic conductivity decreased. For the same water content, the unsaturated hydraulic conductivity decreased and the suction head increased. The pre-acid application characteristic curves can be used to estimate the corresponding post-acid application curves. (C) 2011 Elsevier B.V. All rights reserved.
