pgm processing and recovery

The recovery mechanism of platinum group metals from
For PGM particles to settle by gravity in the experimentally observed timescale they need to be of the order of 200 μm. 2. PGM particles cannot easily be observed directly in the autocat and the best estimates of their size is 1–20 μm. This must mean that the recovery process cannot be driven from the fall of PGM droplets by gravity.

Recovery and Then Individual Separation of Platinum
Recovery of PGMs (especially rhodium platinum and palladium) from different spent manufactured products (like catalytic 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 catalytic converter was primarily processed by crushing grinding and then treating in a hydrogen atmosphere.

Refining Approaches in the Platinum Group Metal
3. PGM Processing and Its Value Chain PGM processing consists principally of four steps (Figure1). PGMs are recovered through underground and open pit mining from poly-metallic sulphide ores 11 . They are initially concentrated by ﬂotation. Conventionally ﬂotation concentrates are enriched by smelting i.e. iron is combined

Recovery of platinum group metals from oxide ores—TML Process
A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores. With the development of a low temperature roasting acidic bromine leaching process by The Minerals Laboratory of BHP Minerals substantial PGM recoveries from oxide and mixed oxide/sulfide ores are now possible.
