How to recover copper from PCB boards?

One ton of scrap electronic circuit boards contains 13% copper, 0.045% gold, and other metals such as iron, palladium, and lead. One ton of waste circuit boards can be refined to 400 grams of gold. A ton of cell phone boards out of about 20 grams of platinum, 520-750 grams of gold, 60-80 grams of palladium, 1.0-1.5 kg of silver, 120-130 kg of copper. This shows that the recovery of copper is very important in the recycling process of waste circuit boards.

At present, circuit board recycling equipment is a good end-of-life PCB separation equipment, can be separated from the metal and non-metallic substances in the circuit board, and then get copper.

Process flow:

First of all, there are many electronic components on the circuit board, first using electronic components dismantling machine, the electronic components on the scrap circuit board dismantled down, dismantled down the electronic components can be sold for a second time, to achieve the recycling of resources;

Then the waste circuit board into the crusher for crushing, the metal and resin for mixed crushing, in order to avoid the metal and resin powder crushing is not enough, we added a special equipment in the rotary sieve, crushing screening, not fully separated from the crushed material will be the second crushing;

After ensuring that the metal and resin powder are all crushed, the airflow specific gravity sorter in the circuit board recycling equipment is used for sorting to obtain high purity copper and resin powder.

The metal extracted from the scrap circuit board can also be refined by electrolysis away from the high-purity copper. Therefore, if you want to make profit by separating the metal in the scrap circuit board, it is recommended to start with dry physical separation of metal and non-metal, because the content of copper in the scrap circuit board is very large, and the market value is very good, you can sell the separated copper to the metal processing plant or sell directly through the scrap circuit board recycling equipment, and non-metal glass fiber and resin powder can also be sold and used to make additives and Filling materials, etc., to achieve low input and high output, the profits are very considerable.
