Gold extraction - QueensMineDesignWiki
Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 % of the gold, under the condition that the ore size is 80 % < 75 µm (Joe Zhou, 2004). Complex ores, meanwhile, require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy, 1994). Finally, refractory ores require additional,Gold processing 101 - Mining Magazine,07/09/2017· At current gold prices this is worth about US$600.
