metals and alloys2. HCl/chlorine leaching gave much improved recoveries of platinum (Pt), palladium (Pd), and rhodium (Rh): Pt (96 per cent), Pd (79 per cent), Rh (28 per cent). Cyanide (ambient temperature) still did not leach PGM well (recovery less than 25 per cent). The reason for this was considered to be passivation of the metal, but the low

Nuclear analytical methods for platinum group elements

noble metals belong to the rare elements. PGE can occur in various oxidation states and exhibit properties of typical transition metals such as catalytic effects, the tendency to form complexes and coloured compounds. The density of PGE is about 12 g/cm3 for the socalled light PGE: Ru, Rh, Pd and around 22 g/cm3 for the heavy PGE: Os, Ir, Pt. Noteworthy are the

The Spaniards named the metal "platina," or little silver, when they first encountered it in Colombia. They regarded platinum as an unwanted impurity in the silver they were mining. The catalytic properties of the six platinum group metals (PGM)– iridium, osmium, palladium, platinum, rhodium, and ruthenium – are outstanding.
