Issues regarding the electrolytic recovery of gold-containing waste liquids

2010-08-05View Original

Thread Content

The gold-containing waste liquid resulting from electroplating in existing electroplating plants typically contains about 0.5 g/L of gold, with a cyanide concentration of around 100–200 mg/L. The traditional method for recovering gold involved adjusting the pH with alkali, adding sodium cyanide, and then using zinc sheets to reduce the gold. Due to environmental concerns, this traditional method is no longer desired; instead, electrolytic recovery of gold is preferred. Those with experience in this area are asked to suggest manufacturers of electrolytic equipment for gold and silver recovery. It would be ideal to find manufacturers that possess complete technologies and equipment for gold electrolytic recovery. If anyone has a similar electrolytic gold recovery process in operation, please share the relevant recovery techniques as well as the type of electrolytic equipment used, along with the manufacturer’s name. Thank you! !

Try to see if it can be reduced directly, or concentrate it first and then reduce it.

Direct reduction – how can it be reduced directly?! Even when attempting to restore it, the restoration is incomplete; the recovery rate is extremely low!

Electrolysis using a gold-containing solution like this is considered to be the best method. As far as I know, there are relatively advanced electrolysis technologies available abroad; however, I couldn’t find any domestic suppliers for such equipment. There must be some suppliers in China though, but the ones I contacted weren’t very good. So I’m hoping to get some advice from fellow enthusiasts – are there any manufacturers that produce high-quality electrolysis equipment, preferably complete sets of such equipment!

I saw at one event the use of imported American electrolysis systems for processing gold-containing waste liquids; such systems cover an area of 2–3 square meters and have a height of 1–2 meters

Yes, we manufacture equipment for the recovery of gold through electrolysis; it can be used with gold-containing solutions of various concentrations, and the gold content can be reduced to 10PPM. For inquiries, please contact 15961451179

It can be reduced using sodium borohydride; this is how we produce it, and the cost is approximately 1 yuan per liter of water.

Advanced electrolysis technologies abroad? What is it? Cyclone electrolysis? ...........

Save it; don’t focus only on the electrolysis approach~~~ Online adsorption, recycling~~~

RENOCELL is good; the cathode is made of carbon fiber and needs to be replaced, and the power voltage and current are adjustable
