(Raymond O.). Recovery of precious metals from electronic scrap. [Washington, D.C.]: U.S. Dept. Recovery of aluminum from electronic scrap by sweating is complicated by the high solubility of precious metals in molten aluminum.

Tests showed that as much as 60 percent of the precious metal content of complex scrap dissolves in the aluminum. The anode mud, see table 9, can be treated by standard procedures for the recovery of the precious metals.

Conclusions. Electronic scrap generated from multiple-pin connectors and the inner assemblies from “black boxes” can be melted to produce a brittle metal that is easily crushed and ball milled to a. Recovery of precious metals from electronic scrap by hydrometallurgical processing requires cyanidation and solvent extraction.

As in primary gold production, cyanide dissolves the precious metals. The metal-bearing liquid is then separated from the barren phase, and the pregnant liquor is contacted with zinc metal (cementation) to precipitate the precious metals.

Additional Physical Format: Online version: Sullivan, Thomas A. Recovery of aluminum, base, and precious metals from electronic scrap. [Washington, D.C.]: U.S. Dept. Since the mids, the trend has shifted toward the hydrometallurgical processing of scrap.
