Abstract
A system and process for bioleaching target metals from sulfide mineral ores and concentrates uses organisms that are genetically modified to produce excessive amounts of amino acids and related compounds, where the organisms are supplied within leach solutions to leach pads comprised of sulfide mineral ores or to leach solutions in CSTRs.
Claims14
A system for bioleaching target metals with genetically modified organisms from sulfide mineral ores or concentrates prepared from finely ground sulfide mineral ores, comprising a bioreactor that produces genetically modified organisms, wherein the genetically modified organisms are used in a heap leach or a continuous stirred tank reactor (CSTR).
A process for bioleaching target metals from sulfide mineral ores and sulfide mineral concentrates, the process comprising:
- producing organisms that are genetically modified to produce excessive amounts of amino acids and related compounds;
- adding the genetically modified organisms to leach solutions;
- and
- delivering the leach solutions to heap leaches comprised of the crushed sulfide mineral ores.
A process for bioleaching target metals from sulfide mineral ores and sulfide mineral concentrates, the process comprising:
- producing organisms that are genetically modified to produce excessive amounts of amino acids and related compounds;
- adding the genetically modified organisms to concentrates prepared from finely ground sulfide mineral ores;
- and
- delivering the concentrates to a continuous stirred tank reactor (CSTR).
