Refining gold is not an easy thing, because not only need a lot of equipment, but also need some chemicals, and gold refining is mainly to remove impurities, improve the purity of gold, which equipment will be used? The following gold refining equipment manufacturers for everyone to introduce in detail.
Circuit board how to refine gold?
Can refine gold electronic waste is mainly gold-containing waste liquid, gold-containing solid waste, gold-plated waste, etc. Gold refining aqua regia purification method requires the disassembly of electronic products, the impurities in the combined gold removal, the impure gold (purity > 90% gold) with aqua regia. Dissolved to generate chlorogold acid, sodium bisulfite as a reducing agent, the chlorogold acid reduction into gold powder precipitation, and then purification, washing, drying, adding flux in high temperature melting and get the color of gold, to achieve pure gold process.
What are the commonly used gold refining equipment?
Large electroplating sets/gold and silver electrolytic recovery machine, fume cabinet, pouring splash machine, glass reactor, aqua regia filtration car, Ph automatic dosing system, reduction and filtration integrated machine, sponge gold filtration drum, PP reduction reaction bus, neutralization tank, gold melting double layer reactor, exhaust gas treatment equipment, etc.
