  • Gold & Platinum Refining by the Salt Water Method ...

    The Catalyst is used to start the dissolving process in the Simplicity Refining System. It’s kind of like a starter motor for a car: once the process starts, as long as the electrical current continues, and as long as there is still gold to dissolve, the metal will continue to dissolve.

  • The Properties and Applications of Platinum

    The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.
