Mechano-chemical Recovery of Platinum Groum Metals (PGMs) from Metal-Foil Supported Spend Auto Catalysts

BACKGROUND Platinum Group Metals (PGMs) are extremely valuable and versatile once recovered. These metals can be used for a wide variety of purposes, including hydrogen fuel cells, electronics, and medical devices such as pacemakers. Historically, used auto catalytic converters have been a valuable source of these PGMs. However, previously used pyro-...

Mechano-chemical Recovery of Platinum Group Metals (PGMs) from Metal-Foil Supported Spent Auto Catalysts

BACKGROUND The used automobile catalytic converter is a valuable source of platinum group metals (PGMs), so it is important to have it recycled to recover precious metals as well as to meet rising industrial demand. Typically, a pyro- or hydrometallurgical method is used for the recovery of PGMs from old automobile catalytic converters. However, these...
