Bioprocessing can be applied in gold recovery/extraction. These processes can be attractive for use on low-grade gold ores that are too expensive to process using conventional processes, and for ores that contain impurities which, in turn, contaminate conventional processing equipment (e.g. arsenic in gold ore).
Sulfide gold ore is a rock gold ore in which natural gold and sulfide (usual pyrite) coexist. The symbiosis of natural gold and sulfide means that pyrite is a gold-carrying body. Under normal circumstances, the sulfides …
Bioleaching and mineral bio-oxidation are in commercial use today (1) in dumps to scavenge copper from run-of-mine rock; (2) in heaps to leach copper from secondary copper ores and to pretreat precious-metal ores in which the gold and silver are locked in a sulfide-mineral matrix; and (3) in aerated, stirred-tank reactors to pretreat precious ...
The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon. Simultaneous leaching and absorption help minimize the problem.
