copper cyanide from gold plant tailings solutions or pulps. AuGMENT is particularly well suited to solutions containing copper cyanide at a low CN:Cu ratio of ~3:1, although it can handle higher CN:Cu ratios by advancing resin more rapidly through the adsorption plant. Copper cyanide is partially eluted from the resin using a strong copper cyanide solution
(rhodium plating) and cyanide based (gold plating). It is very important to separate these two plating solutions as It is very important to separate these two plating solutions as acids and cyanides as they can combine to form hydrogen cyanide gas, which is lethal.
