Electronic waste is generally disassembled into circuit boards, cables and wires, cathode ray tubes, etc., and processed separately according to their respective composition characteristics, with similar processing procedures.

Commonly used recycling technologies mainly include mechanical processing (including disassembly, crushing, sorting, etc.), hydrometallurgy, pyrometallurgy or a combination of several technologies.

1. Recycling process of waste circuit boards

It is divided into the reuse of electronic components and the sorting and recycling of metals, plastics and other components. Generally, the electronic circuit boards are crushed and plastics, copper and lead are sorted out from them.
