THE PRIMARY PRODUCTION OF PLATINUM GROUP METALS (PGMs)

The six platinum group metals (PGMs) occur together in nature alongside nickel and copper. Mineable deposits of PGMs are very rare, with annual production amounting to around 400 tonnes, several orders of magnitude lower than many common metals.

How Is Platinum Extracted? Reference

Once it has been mined, the platinum is extracted from the ore in the same way. The platinum ore is not pure, so it is first crushed. This produces many tiny particles that can be treated. Air particles then bubble through an aeration tank and adhere to the platinum particles. This brings the platinum particles, with the air particles, up to the top of the tank.
