In order to extract the platinum from within a catalytic converter, the converter must be removed completely from the vehicle. Most catalytic converters simply bolt on to a vehicle's exhaust system with a series of threaded bolts. Loosening and then removing these bolts with a simple socket wrench allows for a catalytic converter to be pulled

The Properties and Applications of Platinum

Aug 21, 2020 Platinum is always found alongside other PGMs. In South Africa's Bushveld complex and a limited number of other ore bodies, PGMs occur in sufficient quantities so as to make it economical to exclusively extract these metals; whereas, at Russia's Norilsk and Canada's Sudbury deposits platinum and other PGMs are extracted as by-products of nickel and copper.
