RECOVERY OF PRECIOUS METALS FROM ELECTRONIC SCRAP by R. O. Dannenberg,1 J. M. Maurice,2 and G. M. Potter3 ABSTRACT The Bureau of Mines investigations described in this report were under taken to devise a process to economically recover precious . Digestion in acids with subsequent precipitation of the precious metal may be used on some scrap items. For high recovery by digestion, the precious metal must first be exposed by grinding if encapsulated in plastic or ceramic. Even then, high recovery Cited by: recovery rate of 95% from contactors by mechanical and chemical processing.  Dunning B. W. Jr. et al () have discussed the recovery of Precious Metals from Electronic Scrap and Solder used in Electronics File Size: KB. Metal recovery from electronic scrap by applying mineral processing physical separation methods has been investigated by Distin (). Scrapped integrated circuits containing 25 weight percent copper pins in a ceramic base .

COMSATS Institute of Information and Technology Lahore Department of Chemical Engineering Synopsis Development of non-hazardous process for leaching of metals from electronic scrap . Identification and recovery of rare metals in electric and electronic scrap: a review An estimate of metal recovery rates of precious and base metals from PWB is given in the. Most Computers & electronic devices contain circuit boards inside that will contain many types of precious metals. Printed Circuit Boards, Connectors and Components have high levels of precious metal .
Since the mids, the trend has shifted toward the hydrometallurgical processing of scrap. The emphasis has always been on the recovery of precious metals, namely gold, silver, platinum and palladium Cited by: Additional Physical Format: Online version: Sullivan, Thomas A. Recovery of aluminum, base, and precious metals from electronic scrap. [Washington, D.C.]: U.S. Dept. Request PDF | Aqueous Metal Recovery Techniques from E-Scrap: Hydrometallurgy in Recycling | a b s t r a c t Waste of electric–electronic equipment (WEEE) with an annual . Aluminum melts at a lower temperature than most other metals and can be separated as a molten liquid in a process commonly called “sweating.” Recovery of aluminum from electronic scrap by sweating is complicated by the high solubility of precious metals in molten aluminum.
