‘Fool’s gold’: Dirty iron ore becomes semiconductor material in surprise breakthrough
SMRTR summary
Researchers at the University of Minnesota discovered that low-purity iron ore from Minnesota's Iron Range can be converted directly into semiconductor-quality pyrite, skipping costly purification steps. Pyrite naturally tolerates impurities without losing its semiconductor properties, potentially enabling cheaper solar panels, batteries, and electronics using Minnesota's already abundant mining resources.
