How Gold Electroplating Is Done Sharretts Plating Company

Gold electroplating is a very safe process when done by professionals. One concern with gold plating, however, is that it masks the other metals. If you have a metal allergy, you may be exposed to the allergen as the gold plating tarnishes and the coating wears away.

Zinc powder replacement gold extracting process Yantai

It is an old cyanidation process. Firstly, add cyanide into ore to leach out minerals, then separate the solid and liquid. Add zinc powder or zinc wire into the liquid and the gold and silver will settle as gold mud via chemical reaction. The gold mud containing high gold and silver will be resmelted to highpure gold ingot. At present, this process as the cyanidation gold extracting method
