Title: (EN) SULFIDE MINERAL CONCENTRATE BIOLEACHING
(FR) LIXIVIATION BIOLOGIQUE DE CONCENTRES MINERAUX SULFURES
Abstract: front page image
(EN) The subject invention pertains to processes for extraction of metals from sulfide mineral concentrates and for production of leaching reagents. In one embodiment, the processes of the subject invention utilize a substrate having a high external surface area. In a specific embodiment, this substrate is a ring and pin polyethylene packing to which the concentrates can be bound. The packing provides high external surface area per unit volume over which the concentrates can be thinly coated. The high density of the packing allows high pulp densities to be achieved while leaving a large pore space, which provides relatively uninhibited flow of leach process solutions.
