Stinking Rich? Human Waste Contains Gold, Research Finds – Time
Deploying an electron microscope, Dr. Kathleen Smith and her team spent eight years unearthing minuscule metal particles in treated solid waste. âThe gold we found was at the level of a minimal mineral deposit,â Smith said, meaning that a similar dispersion in rock would be profitable enough for traditional mining. Other metals recovered include silver…
