The final gold extractions for the gravity tailing cyanidation tests on MET-1 and MET-2 yielded 91% and 89%, respectively. Based on the high amount of gold recovered by gravity (25%), incorporating gravity separation into the flowsheet would reduce the size and cost of a plant. The cyanidation kinetic tests indicate very fast gold leaching rates.

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 m (Joe Zhou, 2004). Complex ores, meanwhile, require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy, 1994).

The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.
