Carbon Adsorption In Recovery Of Gold

The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and removed from the carbon surface. At this point, the NaOH/CN solution is sent to electrowinning cells, where the gold is plated onto stainless steel cathodes.
