A method of producing bioproducts which includes the steps of establishing an environment wherein microorganisms oxidise a slurry containing metal sulphide minerals, supplying a feed gas containing in excess of 21 % oxygen by volume to the slurry, and extracting bioproducts from the slurry. The bioproducts may be microorganisms or their metabolites, proteins or enzymes, or both in admixture. They may be of known or unknown constitution. |
