ABSTRACT:
Disclosed is a continuous refractory ore bioprocessing apparatus for the digestion of metal ore with bacteria. It includes a long trough tank fitted with a screw conveyer that extends along the length of the tank. A shell, having a number of feed ports, covers the screw conveyer. Granules of ore to be bioprocessed pass through the feed ports toward the screw conveyer portion of the reactor wherein the ore is ground by the screw conveyer and is bioprocessed as the screw conveyer rotates to push the ore along the reactor. Gas distribution manifolds are attached to the tank and are configured so that gas may be injected into the tank and onto the surface of the shell so as to encourage agitation of the materials in the tank and in the screw conveyer portion of the bioreactor while discouraging fouling of the shell and clogging of the feed ports.
