Web 1 remove the gold bearing connections and edges from scrap circuit boards using pliers and a strong back and forth motion to break the gold fingers from the edge. To prevent the loss of precious metals and the formation of dangerous metal fines, dust containing brominated flame retardants and dioxins during the shredding or grinding pretreatment [2, 22, 30], the waste pcbs were pretreated by microwave pyrolysis prior to hydrometallurgical metal recovery processes. The leaching reaction with thiosulfate, however, is very slow, and to occur the process requires the presence of copper and ammonium.
