Platinum-Group Element - an overview ScienceDirect Topics

Platinum-group elements occur mainly in or near sulphide minerals in an ore deposit. They are typically dissolved in pentlandite [(Ni,Fe) 9 S 8], or present as distinct mineral grains, for example, as braggite [(Pt,Pd)S].The minerals containing platinum-group elements are often attached to or occluded by grains of pentlandite, pyrrhotite [Fe 8 S 9] and chalcopyrite [CuFeS 2].

Platinum-Group Metal Ores - an overview ScienceDirect Topics

Srdjan M. Bulatovic, in Handbook of Flotation Reagents: Chemistry, Theory and Practice, 2010 Publisher Summary. This chapter discusses various aspects of PGM (platinum group metal) ores. In general, PGM ores are concentrates in the crust found in two different ways, by leaching the metal-rich lava (mantle) deposited into the crust, which is known as chemical weathering, especially in a hot ...

Platinum group, six metals, in order of increasing atomic weight, ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), and platinum (Pt). The elements all possess a silvery white colour—except osmium, which is bluish white. The chemical behaviour of these metals is paradoxical in that they are highly resistant to attack by most chemical reagents yet, employed as catalysts ...

History of PGM - PMM - Johnson Matthey

In England, Percival Norton Johnson began work on refining the platinum group metals. He took as his apprentice in 1838 George Matthey, and this collaboration gave birth to the partnership of Johnson and Matthey in 1851. The two men perfected the techniques of separation and refining of platinum group metals and the melting and casting of pure and homogeneous ingots.
