ABSTRACT:
An apparatus for use in bioleach processing of metal-bearing solids is disclosed. The apparatus includes a containment means adapted for containing a slurry made up of metal-bearing solids, a predetermined quantity of water, oxygen, carbon dioxide, nutrients and a species of microorganisms capable of oxidizing some portion of the metal-bearing solids and obtaining energy for growth from that oxidation. The apparatus further includes a plurality of horizontally oriented porous, flexible membrane diffusers adapted for introducing oxygen into the bottom of the reactor vessel in the form of small widely dispersed bubbles.
