Extracting metals from scrap electrical appliances is a job that requires caution and knowledge. Here are some tips to help you extract more efficiently: 1. **Safety preparation**: - **Wear protective gear**: Make sure to wear gloves, goggles and masks to prevent injury or inhalation of harmful substances. - **Working environment**: Choose a well-ventilated place for disassembly and avoid operating in a closed or humid environment. 2. **Prepare tools**: - Prepare the tools you need, such as screwdrivers, pliers, wrenches, hammers, power tools, etc. - If possible, using power tools can improve efficiency, especially when disassembling some large appliances. 3. **Classification disassembly**: - **Classify electrical appliances into different categories**: such as home appliances (TVs, refrigerators, washing machines, etc.), small appliances (microwave ovens, electric shavers, etc.). - **Identify metal parts**: When disassembling, pay attention to identifying which are metal parts, such as the outer shell, internal frame, wires, etc. 4. **Disassemble appliances one by one**: - **Proceed in the disassembly order**: First remove the outer shell of the appliance, and then disassemble the internal parts step by step. - **Find separable metals**: Some metal parts may be connected and can be opened with pliers or manually pried apart. 5. **Extract various metals**: - **Classify and store**: Sort the extracted metals by type, such as aluminum, copper, stainless steel, and iron. This will make it easier to process or sell them later. - **Separate mixed metals**: If there are precious metals (such as gold and silver), pay special attention to separate them. 6. **Dispose of waste**: - Don't forget to properly dispose of the remaining plastic, glass, and other non-metallic parts. You can consider recycling or contacting a local waste recycling center. 7. **Understand local laws and regulations**: - When extracting and selling metals, understand local laws and regulations as well as environmental requirements to ensure that your actions are legal and safe. Finally, extracting metals from scrap electrical appliances requires not only patience, but also a certain understanding of the internal structure of the appliance. If you are not familiar with how the appliance works, it is recommended to do some research or consult a professional first.
