Abstract

Disclosed is a process and apparatus for conducting bio-oxidation processes for the extraction of metals from metal containing materials in which aeration means, preferably a diffuser means, is employed within a bio-oxidation reactor to maintain bacterial viability and suspension of metal containing materials by introduction of an oxygen containing gas to a non-mechanically agitated reactor.
