In other locations, platinum is simply extracted from copper and nickel as a byproduct. The extraction process involves crushing, froth flotation, skimming, drying, heating, application of chemical and electrolytic measures, dissolution in aqua regia, chemical conversion and burning. Fortunately, once extracted, platinum can also be recycled.
