SEPARATION OF PLATINUM GROUP METALS

Prior proposals to use chromatographic separation for platinum group metals include USP 4,855,143 (Schmuckler) and EP 756013 (Matthey Rustenburg Refiners (Pty) Ltd). The latter represents a major step forward in the design of practical separation methods, but there remains a need for an improved method which is capable of the treatment of actual feedstocks from a PGM refinery, which are ...

25/09/2019 · Recovery of PGMs (especially rhodium, platinum, and palladium) from different spent manufactured products (like alytic converters) is considered as an important task as they are rarely found in nature, and they possess high economic value. In this work, the honeycomb of a car alytic converter was primarily processed by crushing, grinding, and then treating in a hydrogen atmosphere.
