The Bureau of Mines, in cooperation with the National Association of Recycling Industries (NARI) and the defense property disposal service, studied recycling problems associated with recovering precious metals from electronic scrap. Specific problems encountered by NARI members included the recovery of platinum-group metals (PGM) from electronic reed switches and telephone relays. The Bureau investigated hydrometallurgical techniques as possible alternatives to pyrometallurgical processes for recovering PGM. In addition, both scrap sources (switches and relays) required some mechanical upgrading to produce fine-particle concentrates ideally suited to hydrometallurgical processing.
