Precious Metal Refining & Recovery, Episode 10: Platinum From the Road

We can literally sweep platinum off our highways, as Cody'sLab demonstrates[0]. Platinum is a catalyst in auto mufflers to change NOx molecules back to N2 and CO2. And a tiny amount flakes off as a gas-car drives. Sweeping a 10-foot section of heavily-used freeway shoulder netted them $0.55 of platinum. At this rate, there should be $1000 of platinum per mile of freeway shoulder. [0] [VIDEO]

Cody's Lab did an episode where he collected and refined freeway dust: it's actually decent grade platinum 'ore' from catalytic converter deposition [VIDEO]

Roads are filthy. Cody's Lab once did a video where he collected road dust from the side of a highway, and refined out all the precious metals from it. That's from one small section of highway, just imagine the scale of the pollution across the whole of the states. Concrete dust, rubber, metals, fuel, oil. Cars and car infrastructure is dirty business. [VIDEO]

Which reminds me of a video of Cody's Lab, where he refines precious metals out of roadside dust: [VIDEO]

There's a Cody's Lab video where they refine highway dust for platinum group metals leaking from catalytic converters: [VIDEO]
