Method and apparatus for extracting precious metals |
| abstract |
A method and apparatus (4) for extraction of precious metals from their ores and the product (26) thereof. Oxidized ore comprising a precious metal is exposed to a leaching solution (lixiviant) (254) comprising a relatively high concentration (activity) of dissolved hydrogen sulfide gas, a relatively high concentration (activity) of bisulfide ions, and a relatively low concentration (fugacity) of dissolved hydrogen gas. The hydrogen sulfide gas and bisulfide ions are preferably added to the solution by sulfate-reducing bacteria growing in a medium comprising dissolved sulfate ions and dissolved nitrate ions, but abiotic sources may also be used. Examples of such bacteria include mesophilic, fresh water species species such as Desulfobacterium catecholicum DSM 3882 and Desulfovibrio simplex DSM 4141; mesophilic, salt-water species such as Desulfovibrio salexigens DSM 2638; and thermophilic; fresh-water species such as Desulfomaculum kuznetsovii VKM B-1805. |
