Open publisher page 1 citations

Abstract

Waste electrical and electronic equipment(WEEE) has received the widespread attention because of its potential environmental hazards and rich in valuable metals. Most of all, the recovery of precious metals from the WEEE is the major economic driving force. The two-stage treatment of precious metals recovery in the WEEE contains pretreatment and extraction, the technical progress of the treatment was introduced, and further summary and outlook were made on the various methods of the two-stage treatment.
