From dust to gold: Recovering precious metals from London street dust

Veolia is exploring the extraction and recycling of precious metals like palladium and rhodium from car exhaust dust. Annually, 300 tons of palladium are produced, with 60% used in catalytic converters. The extraction process involves magnetic separation and conveyor belts to isolate metal traces from street dust.
