How to Gold Recycle from Electronic Circuit Board Scraps

In this video, we're going to show you how to recycle electronic circuit board scrap into gold. By following these simple steps, you'll be able to recover a large amount of gold from your scrap.

Electronic circuit board scrap is a great resource for gold recovery, and this video will show you how to take advantage of it. By following these steps, you'll be able to turn your scrap into gold, and build your wealth in the process!

Use 68% nitric acid mixed with water in a 1:1 ratio to separate gold from old circuit boards. a simple way

After the gold has been dissolved, use a filter paper or other filtering device to separate the gold from the acid solution.

It's important to note that this process can be dangerous, as both nitric acid and hydrochloric acid are highly corrosive and can cause serious injury if they come into contact with skin or eyes. Therefore, it's important to take proper safety precautions, such as wearing gloves and goggles, when working with these chemicals. and should only be carried out by trained professionals. It is also important to follow proper safety procedures and regulations when working 

You can see the gold stripes coming off the PCB.

But these golds are not pure enough that the market needs to solve these problems with Aqua regia acid.

Aqua regia recipe and recipe

Since aqua regia is just a mixture of two strong acids, it doesn't have a chemical formula of its own. However, it can be represented as

Aqua regia solution is usually a yellow, reddish-orange, fuming liquid and has a rapidly changing composition. The traditional aqua regia solution is comprised of a 3:1 molar mixture of hydrochloric acid and nitric acid, respectively.

Note that concentrated nitric acid is about 65% and concentrated hydrochloric acid is nearly 35%, so the volume ratio is generally 1 part of concentrated nitric acid to 3 parts of concentrated hydrochloric acid.

Use sodium metabisulfite precipitate gold out of a aqua regia solution.

You will get gold sludge powder. Then cleaned the gold sediment, dried and melted into cubes. Sprinkle a little borax powder.
