Abstract: Provided are non-limiting embodiments of a wear-resistant impeller having a non-conventional blending provided between a surface of a vane (1) and a surface of at least one of a front side shroud (15) and a rear side shroud (16). The impeller may comprise both a rear side blending (3) and a front side blending (2), and the front side blending (2) may comprise a different geometry from the rear side blending (3). The blending preferably comprises a bulbous geometry which is uniquely adapted for optimizing flow patterns adjacent to the vane and between the front and rear side shrouds in a manner which discourages the formation of horseshoe vortices proximate the leading edge (6) of the vane (1) during operation. Through the reduction, mitigation, or elimination of horseshoe vortices, local high velocities and turbulence are generally minimized, and wear experienced by portions of the impeller (e.g., to one or more vanes) from flows of abrasive slurry can be reduced. Accordingly, the useable life of an impeller may be improved.

Abstract: A system and method for improving leach kinetics and recovery during above-atmospheric leaching of a metal sulfide is disclosed. In some embodiments, the method may comprise the steps of: (a) producing a metal sulfide concentrate [34] via flotation; (b) moving the produced metal sulfide concentrate [34] to at least one chamber [22a] of at least one reactor such as an autoclave [20]; (c) leaching the produced metal sulfide concentrate in said at least one chamber [22a] in the presence of oxygen [82] at a pressure and/or temperature above ambient, and in the presence of partially-used [25] and/or or new [92] grinding media within the at least one chamber [22a]. Systems [10] and apparatus [20, 200] for practicing the aforementioned method are also disclosed.
