Method for refining gold from waste circuit boards
There are two ways to extract gold from waste circuit boards, let’s find out together!
1. Traditional chemical solvent method:
Using chemical properties, put the solvent into water to soak the waste circuit board, then heat the added chemical solution at 100-200°C, and leave it for about 1-2 hours, you can see the golden element floating at the bottom of the container, which is the extracted gold , The method of extracting gold with chemical solvents has relatively small processing capacity and low efficiency. It is easy to produce waste water and waste gas to pollute the environment, and it will also cause the loss of some metals and waste of non-metal resources, which is time-consuming and laborious.

2. New equipment separation method:
The circuit board recycling equipment is used for separation and extraction. This equipment adopts a new type of dry physical separation technology to extract metal elements in waste circuit boards through crushing, separation, and sorting, and then further extracts gold from them.
Waste circuit board recycling equipment This method avoids the shortcomings of the traditional separation method, and directly performs dry crushing and sorting according to physical properties. The process will not produce waste water and waste gas to pollute the environment. In addition, the equipment is also equipped with pulse dust removal. The device, when the circuit board recycling equipment is processing waste cables, realizes fully enclosed operation without any dust leakage, and is an environmentally friendly metal purification equipment.
In the process of processing waste circuit boards through circuit board recycling equipment and then extracting gold, other non-ferrous metals, such as silver, copper, aluminum, etc., can also be obtained. The quality of the obtained metals will not be damaged, and the extracted Metals can be sold directly to metal processing factories to achieve secondary use of resources. In addition, non-metallic resin powder separated from waste circuit boards can also be sold, often used as wood additives, etc. Equipment separation and extraction of metals can be effective Recycling and reuse of resources will not cause waste of resources, and it is more environmentally friendly than traditional separation methods. It not only saves labor costs, but also increases production.
The traditional method of extracting gold has a great impact on environmental pollution, and is time-consuming and labor-intensive with low efficiency. Therefore, the most commonly used method is to extract it through waste circuit board recycling and processing equipment.
