How Is Platinum Mined History Techniques and Photos

These are all extracted during the mining process. Because of the rarity of pgm and its tendency to combine with other metals, the mining process often yields far more nickel or copper than it does platinum. In South Africa, the world’s largest producer, platinum is mined in an area called the Bushveld Igneous Complex.

How Is Platinum Extracted From a Catalytic Converter?

Once the platinum-coated catalyst material has been removed from a catalytic converter, the platinum can be removed from each individual piece of catalyst. The platinum, which appears as a silvery, bronze color located on the outer surface of each piece of catalyst, can be picked and peeled off by hand or by using a flat-head screwdriver or pair of box cutters.

Platinum Refining Process

Platinum scrap such as platinum coins, palladium PD and platinum wire is weighed and then smelted. As the platinum scrap liquefies in the furnace or melts under a blowtorch, flux is mixed in to separate the pure platinum from other precious and non-precious metals. A sample is removed for assaying, which is the process of measuring the platinum
