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. [22] Dunning B. W.
