Solved For many years, the recovery of gold
For many years, the recovery of gold – that is, the separation of gold from other materials – involved the use of potassium cyanide: 4Au + 8 KCN + O2 + 2H2O -->4KAu(CN)2+4KOH (a) What is the mole ratio of KCN and KOH? Au and KCN ? (b) What is the minimum amount of KCN in moles needed to extract 29.0 g of gold?
Potassium dicyanoaurate
Potassium dicyanoaurate (or potassium gold cyanide) is an inorganic compound with formula K[Au(CN) 2].It is a colorless to white solid that is soluble in water and slightly soluble in alcohol. The salt itself is often not isolated, but solutions of the dicyanoaurate ion ([Au(CN) 2] −) are generated on a large scale in the extraction of gold from its ores.

Gold Plating, Making of Gold Potassium Cyanide
If you want to use eplating using gold potassium cyanide you will have to take a lot of safety precautions. The method I use is much simpler. I have experience with eplating thin layers of gold on top of gold and palladium substrates (thin is anything between 100nm and a few microns). I use a commercially available eplating kit which is very ...
Goldsmithing Use of Cyanide
Basically you put the jewelry into a solution of potassium cyanide and then pour in some peroxide and this leads to an effusion of cyanide gas and a boilover, hence the name bombing. The process actually removes some gold and leaves a clean, pure gold layer. This should be done under a fume hood or outside, as cyanide gas is released. -royjohn
