Google – Patent US4321145 – Ion exchange treatment for removing toxic metals and cyanide values from – Google Patents
Acidic waste flows developed during regeneration steps are, when desired, further treated to recover cyanide values therefrom by heating same within a generally closed tank to drive off a hydrocyanic gas, which is then reacted with caustic within a circulation reactor having an inclined passageway in order to form and …
Recovering gold from electronics, page 3 – Removing gold from electronics, page 3
In a perfect set-up, you "might" recover 6 to 10 troy ounces of gold from a ton of high grade scrap, the costs to recover the gold run will run about $3000 a ton, leaving you a net of about $3000 on the high side, and guys trust me, the set up to effectively process a ton of scrap is not cheap.
