A new video from Cody s Lab explains why a significant amount of this precious element exists in the dirt and dust by the roadside — and shows how it can be extracted.
Of course, mining it will take a bit of sweeping and a lot of chemistry.
Basic math tells us that this wastage adds up over time, particularly along high volume stretches of road such as highways.
After putting it through a number of tests and chemical processes, the two were able to confirm that you can find platinum by the side of the road, and all that seemingly useless dirt actually contains some very valuable ore.
Platinum, which is used in everything from catalytic converters and lab equipment through to thermometers and jewelry, is one of the rarer elements in the Earth s crust.
Only a few hundred tons are produced annually, making it an major precious metal commodity.
