Abstract: A method and apparatus for anaerobic oxidation of metal sulfides in ores and concentrates. Base-metal and precious-metal ores and concentrates often contain metal sulfides, such iron sulfides (e.g., pyrite, pyrhotite, arsenopyrite, etc.), copper sulfides (e.g., chalcopyrite, chalcocite, etc.), zinc sulfides (e.g., sphalerite, etc.) and/or lead sulfides (e.g., galena, etc.) and/or other metal sulfides), that must be oxidized in order to recover metal values (e.g., gold, silver, or platinum group elements) from the ores. In the present invention, these metal sulfides are oxidized in one reactor under anaerobic or anoxic conditions using oxidized metal ions, such as ferrous ions (Fe.sup.+3), as the oxidizing agent. Anaerobic oxidation of elemental sulfur that is produced by metal sulfide oxidation is biocatalyzed by sulfur-oxidizing bacteria, such as Thiobacillus ferrooxidans, Thiobacillus thiooxidans, or or Sulfolobus sp.

Abstract: An apparatus and method for anaerobic and aerobic respirometry. The apparatus and method provide for automatically collecting and analyzing the data required to calibrate mathematical models for bioprocesses that involve anaerobic respiration, aerobic respiration and dehalogenation. Dissolved electron-acceptor concentrations and/or product concentrations and/or headspace pressures are automatically monitored during the progress of a biotransformation occurring in a batch reactor to produce a data set. The data set is analyzed to derive intrinsic kinetic parameters and stoichiometric coefficients. The cultures biocatalyzing the oxidation-reduction reactions of interest may be aerobic, denitrifying (e.g., nitrate-reducing), sulfate reducing and/or methanogenic. The models thus developed may be used for design of wastewater treatment or bioremediation processes.
