The extreme rarity of the platinum group metals makes them a very valuable commodity in a number of industries; they are just too precious to lose. The platinum group metals (PGMs) we refine are:

  • Platinum (Pt)
  • Palladium (Pd)
  • Rhodium (Rh)
  • Ruthenium (Ru)
  • Iridium (Ir)

JewelleryAs well as these, we also refine:

  • Gold (Au)
  • Silver (Ag)

The majority of the final products are in the the form of a powdered 'sponge'. Gold and silver are made into a course grain by pouring the molten metal into water.

 Everyone is familiar with the role of gold, silver and platinum in jewellery and decorative objects but that is just one facet of these metals' use.
