Our plants are designed for the production of high quality Gold potassium cyanide (GPC) 68% K[Au(CN)2]. We realize plants of different capacity, according to customers'' request, from 3 kg to 10 kg per batch (the duration of a production cycle is about 8 hours).
Feb 21, 2012· In its purest form, which is usually used in acid gold baths, the PGC will contain about % gold. If it is used for cyanide baths, it might also contain some potassium cyanide, which would lower the gold percentage. If it is used for acid baths, it could also contain a little nickel or cobalt and will have a green or pink color.
The invention relates to gold potassium citrate for gold plating and a preparation method thereof. The gold potassium citrate is used to substitute for gold potassium cyanide in acidic and neutral gold plating technology. The problem that the product coverage area is too wide when gold citrate is used in the gold plating technology is solved.
Gold potassium cyanide is obtained by the anodic dissolution of gold in an aqueous solution of the compound potassium cyanide, followed by crystallization of the entire mixture. In addition, the gold potassium cyanide mixture contains approximately 68% fine gold which appears to be a fine powder that is readily soluble in water.
Nov 03, 2009· (3) If the PGC is of the % variety, it would help the gold precipitation to also dissolve about 15 grams of potassium cyanide per liter in the solution. Without the extra cyanide, you may or may not have a problem dropping the gold. The gold may finally drop, but it will be slower. It is best to add the extra cyanide.
