Alkaline Pressure Oxidation of a GoldBearing Arsenopyrite Concentrate

Alkaline pressure oxidation at l60°C, 2413 kPa O 2 and 2 M NaOH resulted in about 98% sulfur oxidation and 86% arsenic dissolution. Cyanidation of the leach residue resulted in 82% Au extraction. This value for gold extraction is lower than what is typically achieved by acid pressure oxidation followed by cyanidation.

Gold extraction QueensMineDesignWiki

Freemilling gold ores are defined as an ore from which standard cyanidation (which takes about 2030 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).

Gold cyanidation Wikipedia

Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.
