recover gold from cyanide anode hode

The direct electrowinning of gold from dilute cyanide . 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 NaOHCN solution is sent to electrowinning cells where the gold is
