Abstract
This report is an investigation of the use of ion exchange resins to recover germanium from acid etch wastes encountered in transistor manufacture.
Most of the experiments were performed with acid etch waste of unknown germanium content. The object was to determine if the ion exchange technique were applicable, and to select the most practical operating procedure.
When a satisfactory procedure had been established, later experimental runs were made with an acid etch solution of known germanium concentration to determine the yields of recovered germanium.
Yields of 60 per cent to 75 per cent recovery of germanium from the etch waste were accomplished by eluting the germanium complex from a weakly base anion resin with a dilute ammonium hydroxide solution.
