The Defense Logistics Agency (DLA) is responsible for the administration of the Defense Precious Metals Program. DLA has established a series of Precious Metals Indicator Codes (PMIC) to indicate the type and relative amount of precious metals in DoD items. DoD item managers are to assign PMICs to all items under their control. Once PMICs are recorded in item managers' supply management data, they will be entered on Disposal Turn-In Documents when items are offered to Defense Property Disposal Offices (DPDO) for disposal. DPDOs will use PMICs to identify those items whose precious metals content is to be recovered for future DoD use. Item managers have not begun the PMIC assignment process. The authors hypothesize that PMIC assignment by item managers using transaction information from the DLA Precious Metals Recovery Management System (PMRMS) will result in significant cost savings for DoD. Significant per item cost savings are shown to occur using the PMRMS method for assigning PMICs; however, the significance of total cost savings accruing to DoD was not conclusively determined. The potential of using Federal Item Identification Guide (FIIG) information for assigning PMICs was also discussed. (Author).

This information circular describes research the Bureau of Mines has conducted to improve technology for recovering precious metals from low-grade resources. Many of the reported findings are recent, and some of te work described is ongoing. Topics discussed include cyanidation of carbonaceous gold ores to enhance gold recovery, a new method for precipitating mercury during cyanide leaching of gold ores, a staged heap leaching process to generate suitable solutions for direct electrowinning of gold, the use of anion-exchange resins to recover gold from cyanide solutions, and precious metals recovery from electronic scrap.
