Therefore, the problem of resource utilization should be fully considered while harmless treatment. In general, the main economic driving force of E-waste recycling is recovery of precious metals, followed by other metal elements, such as copper, cobalt, nickel, lithium, etc. The technology of extracting precious metals and other valuable metals from E-waste through chlorinated pyrometallurgy and chlorinated hydrometallurgy was introduced emphatically.
