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...

Novel solution for "produced water" disposal

BACKGROUND Water is used to extract oil and gas through hydraulic fracturing. This results in large quantities of Produced Water that needs to be dealt with. Produced water has considerable management costs that could adversely affect the life of the well. Produced water handling practices must also be environmentally sound or the operator could...
