How to recover gold from cyanide solution
Recovering gold from cyanide solution is a very old method, and, it is still employed in large scale recovery of gold from its ores. Oxygen also plays an important role in the leaching of gold in a cyanide solution. This fact is very much utilized in the gold extraction in private and government refineries. Big cement, iron or wooden vats with false bottoms having holes and canvas matting are filled with the washed ores. It is a solution of 0.3% of potassium cyanide that percolates continuously from 12 to 24 hours. Once the gold is completely removed from ores, the metal gold is precipitated by fresh zinc shavings.
Ever since people started realizing the potential of recycling gold from e-waste, they also started looking for methods about how to recover gold from a cyanide solution. People are interested in this method because it is very economical. Mostly what people do to recover gold from different gold plated connectors, golden fingers, CPUs, different types of jewelry is that they either treat them with nitric acid or aqua regia and thus the metals-copper, nickel or brass go into the solution, and they don’t recover these metals from the solution. They only care for gold. But if you recover gold through cyanide process you can save copper, nickel and brass also and increase your profit considerably.
A lot of people want to know how to recover gold from cyanide solution because they see a great number of people making huge profits through removing gold from many gold-plated items using cyanide. Everybody keeps their business secrets. That’s why nobody tells the other person as to how exactly he is extracting gold through cyanide process.
But we can assure you, gold recovery through cyanide can be done on a small scale also both chemically and electrolytically, but great care should be taken as cyanide is poisonous in nature. If one has to use cyanide process for gold extraction, never use laboratory grade always use commercial grade and use sodium cyanide instead of potassium cyanide that is less risky. I have seen gold electroplaters gold plating jewelry or doing reverse plating using sodium cyanide of commercial grade. It works wonders if handled properly. You can also achieve the best results if you maintain the temperature of the cyanide solution and regular flow of oxygen into it. After using the cyanide solution for recovering gold, we must make sure to neutralize it. For this, many companies sell chemicals with all the necessary instructions.
Our company is in this line for a very long time. If you ever need any kind of help, please feel free to contact us. We will try our level best to solve your problem. Not just about gold recovery through cyanide, we can also help you out with other very simple and economical gold recovery methods from different materials such as motherboards, hard drives, electronic circuit boards used in c-dot or mobile exchange from which we get comparatively more gold, cell phone scrap (which is also a good source of gold recovery.), CPUs, computer rams, display and sound cards etc.
