Methods for recycling and reusing discarded electronic circuit boards

At present, the waste circuit boards on the market are mainly circuit boards for home appliances, computers, etc. Therefore, they can be divided into several categories for recycling. Those with electronic components need to be disassembled manually first, and then disassembled and recycled by circuit board recycling equipment, while those without electronic components can be directly crushed and recycled.

 At present, the recycling of waste circuit boards has become an industry with far-reaching significance for social development. Recycling waste circuit boards can reduce resource waste, environmental pollution and other problems. The equipment and processes for physical recycling of waste printed circuit boards mainly include the crushing and dissociation of waste printed circuit boards, and the separation of metals and non-metals using dry and wet separation technology.

Research has found that when the waste motherboard is crushed to 1~2mm, it can basically be dissociated, and the crushed product contains about 6% copper, about 18% other metals, and about 76% non-metals; copper is mainly distributed in powders <0.5mm, and metals are mainly distributed in particle sizes >0.5mm; high-frequency airflow separators can effectively separate non-metals from metals, and its separation particle size range is wide, the separation lower limit is low, and the operating cost is low. It is an ideal dry separation method.
