Abstract: The bulk volume of large numbers of loose, separated, multiply bent, irregularly shaped scrap sheet metal is temporarily reduced, for transportation and storage of the metal for recycling purposes, by compressing the metal into temporary, compacted wafers formed of successively compacted layers. The apparatus includes a load chamber which is axially aligned with a compression chamber and a reciprocating ram which passes through the chambers towards an anvil plate which closes the discharge end of the compression chamber. A pre-determined quantity of loose pieces is placed within the load chamber. The reciprocating ram compresses the pieces of that batch into a thin layer. Successive batches are compressed into overlapping layers which are temporarily bound together, face-to-face, to form a unitary wafer, by temporarily bending and intertwining the peripheral edges of the layers. The layers are subsequently separated for recycling by depositing into a melt furnace.

Abstract: The present invention springs from the discovery that mild acids could be utilized to shear undesired metals away from desired precious metals that have been plated onto circuit board runners or contacts. This shearing action occurs at a high rate when metal scrap segments are immersed in mild acid and excited by application of an electromagnetic field at specific frequencies and power levels. These frequencies and power levels are based on the end metal desired and the metals contained in the scrap and the acid utilized. When mild acid saturated with copper sulfate and loaded with scrap metals is subjected to an electromagnetic field at the appropriate frequency and power levels copper and nickel molecules are sheared rapidly and absorbed into solution, leaving only the desired metal, such as gold, in a 99.5% pure flake which can be skimmed off the surface of the solution or filtered from the solution.
