Abstract
Systems for improving metal leach kinetics and metal recovery during atmospheric or substantially atmospheric leaching of a metal sulfide are disclosed. In some embodiments, an oxidative leach circuitmay employ Mechano-Chemcial/Physico-Chemical processing means for improving leach kinetics and/or metal recovery. In preferred embodiments, the Mechano-Chemcial/Physico-Chemical means comprises various combinations of stirred-tank reactorsand shear-tank reactors. As will be described herein, the stirred-tank reactorsand shear-tank reactorsmay be arranged in series and/or in parallel with each other, without limitation. In some non-limiting embodiments, a shear-tank reactormay also be disposed, in-situ, within a stirred-tank reactor
