Abstract

The invention discloses a waste mobile phone recycling method. The waste mobile phone recycling method comprises the following specific steps: S1, collecting waste mobile phones; S2, cleaning; S3, disassembling; S4, recycling plastics; S5, recycling sheet copper in spent lithium-ion batteries; S6, performing secondary crushing treatment; S7, separating; S8, crushing circuit boards; S9, recycling nonferrous metals of circuit boards; S10, separating and recycling mobile phone screen polarizer films. According to the strictly controlled waste mobile phone recycling method, recycling of waste mobile phones is realized, the plastics is effectively recycled, and meanwhile nonferrous metals in lithium-ion batteries and circuit boards are effectively separated out to be recycled, the pollution of waste mobile phone materials to the environment is avoided; besides, the waste mobile phone recycling method has the advantages of reasonable design, high safety and practicability, and therefore the method can be popularized and used widely.

Description

Technical field [0001] The invention relates to the technical field of waste mobile phone recycling, in particular to a method for recycling waste mobile phones. Background technique [0002] Used mobile phones are mainly composed of plastic casing, lithium battery, circuit board, display and other parts. These components contain lead, chromium, mercury and other toxic and harmful substances. If they are improperly handled or discarded at will, they will seriously pollute the soil and groundwater, posing a huge threat to human health. Waste circuit boards also contain brominated flame retardants such as polybrominated biphenyls and polybrominated diphenyl ethers, which are carcinogenic, teratogenic, and mutagenic. Plastics can also produce harmful gases during the combustion process. Waste mobile phones contain a small amount of valuable metals, especially precious metals, which have reutilization value. A study shows that theoretically, 0.45 kg of gold, 130 kg of copper and 2...
