    Alkaline cyanide bathsfor gold and gold alloy plating are the oldest types of gold baths, but their importance in industrial coating has been diminished. The coating is matt or semibright. Gold is added as potassium gold cyanide, and some free potassium cyanide and carbonate exists. Phosphates and hydroxides can be added to improve conductance.

    How to Make Gold Plating Solution. 3 Steps Instructables

    Step 3: Final Step, Making Gold Plating Solution. In the final step, we need to make a strongly alkaline solution of gold chloride and potassium ferrocyanide. Using this solution and electrical current, we can deposit gold over the surface of other metals. This solution contains gold cyanideions, which are extremly poisonous.

    Feb 22, 2011· Most plating of gold and its alloys is carried out from solutions containing gold as a soluble cyanide complex. Gold reacts with alkali cyanides to form eithermonovalent(MAu(CN)2) or trivalent (MAu(CN)4) complexes, wherein M is an alkali metal or, in some cases,ammonium ion. Gold plating solutions, as originally configured, contained some excess of free alkali cyanide, which served …

    May 11, 2014· You should have no problem recovering gold using strong base anion resin. The only strong "chelator" in most gold baths is cyanide, unless you are using a sulfite system, or you have a acid gold chloride strike. The gold is in the form of a gold cyanide complex which exchanges quite nicely. And free cyanide comes out on the SBA resin as well.

The problem is that gold plating has been around for 170 years, and is very technically pliable, so that just about anything you can achieve with alkaline cyanide gold you can do with acid gold and vice versa. Although most acid gold is still cyanide based, there is less cyanide so it's probably somewhat safer to work with.

    I have seen gold electroplaters gold plating jewelry or doing reverse plating using sodium cyanide of commercial grade. It works wonders if handled properly. You can also achieve the best results if you maintain the temperature of the cyanide solution and regular flow of oxygen into it. After using the cyanide solution for recovering gold, we must make sure to neutralize it.
