How to remove gold from circuit boards without chemicals?

We all know that circuit boards can extract gold, many enterprise use chemical and physical methods to extract gold, but there will be a lot of toxic substances, so the best method is to use environmental protection method instead of chemical to extract gold.

But how to use environmental protection equipment to recover gold from circuit boards is an international problem in the last few years. However, our company produces environmental protection equipment to use new technology to recover gold from circuit boards to solve this problem.

The new process adopts wet full dissolution or selective dissolution and activated carbon adsorption to recover gold from printed circuit board containing trace gold. after dissolution, adsorption, refining, drying and smelting, the gold content of the product can meet the national standard gold standard.

Printed circuit board recycling

The technology, which treats circuit boards, can extract act 30 kilograms of gold from more than 100 tons of circuit boards. It is worth more than 3 million yuan. Not only that, the refined slag can be mixed into sand and stone to make slag brick in a certain proportion, and become high-quality wall building materials. What’s more, even can use the powder made of PCB board to make handicrafts, without solid waste discharge. That is to say, the problem of high cost, serious pollution and waste of resources in extracting gold by chemical methods is completely avoided.

The process to remove gold from circuit boards

At present, the value of metal and non-metal resources contained in the waste circuit boards produced in the global market every year is up to 100 billion yuan, of which the price of gold is immeasurable. For this reason, environmentally friendly equipment is particularly important to replace the chemical method of extracting gold. it can turn e-waste into treasure and produce good economic and social benefits, and has an extremely broad market prospect.
