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).

The Carbon-in-Pulp (CIP) gold processing technology has enabled a rapid, world-wide growth in gold production. As a result, gold is one of the few winners for the mining industry in the 1980's. The key step in the CIP technology is the adsorption of the gold(1) dicyanide ion, Au(CN)2-, onto coarse carbon granules.
