# An efficient way to extract waste electrical metal by yourself If you want to extract metal from waste electrical appliances, here are some ways to improve efficiency： ## Basic preparation -Wear protective equipment: gloves, goggles and masks to avoid contact with harmful substances -Prepare appropriate tools: screwdriver set, pliers, wire cutters, small hammer and collection container ## Efficient classification method 1. **Preliminary classification**: Group electrical appliances by type (circuit board, wire, metal shell, etc.) 2. **Metal separation**: Store different metals separately (copper, aluminum, steel, etc.) -Copper: usually reddish brown, present in wires and motor windings -Aluminum: light and silver-gray, commonly used in heat sinks and housings -Steel: heavier and magnetic ## Extraction technique -**Wire handling**: Use wire strippers to quickly peel off the plastic skin to obtain copper wire -**Circuit board**: Centralized collection of circuit boards containing precious metals such as gold, silver, and palladium -**Transformers and motors**: A large amount of copper wire can be obtained after disassembly -**Use magnets**: quickly separate iron and non-iron metals ## Safety tips -Avoid disassembling parts containing hazardous substances (such as CRT tubes, capacitors, etc. for old-style displays) -Do not perform chemical extraction at home (such as extracting metals with acid), it is dangerous -Do not burn electronic waste to extract metals, which will release toxic substances You may get a better return by selling the sorted metal directly to the recycling bin instead of trying to purify it further.
