DID YOU KNOW? PGMS

Platinum group metals or PGMs are six noble, precious metal elements clustered together in the D block of the periodic table (transition metals). PGMs have similar physical and chemical properties and are mined from the same mineral deposits.

The six elements in order of increasing atomic weight are ruthenium, rhodium, palladium, osmium, iridium and platinum. Known for their purity, high melting points and unique catalytic properties, they are also extremely resistant to corrosion.

Consumer and industrial products made with platinum and other PGMs include flat panel monitors, glass fibre, medical tools, computer hard drives, nylon and razors. Platinum, palladium and rhodium play a critical role in autocatalysis and automotive pollution control. 

South Africa has more than 80 per cent of the world's platinum reserves and is the world's largest producer of platinum group metals.
