Gold has always been valuable. Today, we use gold not only for jewelry, but in other industries like medicine and technology. But what was rare before has become rarer still, since we are discovering fewer and fewer gold deposits as time goes on, much like we are with other natural resources. And while the gold industry typically extracts this prec...
It turns out that flaws in pyrite are the key to containing gold. Fougerouse and his team found that pure gold can be held inside nanoscale crystal defects called dislocations. “The more deformed the crystal is, the more gold there is locked up in defects,” Fougerouse says. It’s no wonder this “invisible” gold has gone undetected all this time–acco...
For gold and possibly other elements, this study could have wider impacts on how we find and extract minerals, especially as they become more scarce and in-demand. RELATED: The Wonderful World of Minerals The typical process for extracting gold from ore, called pressure oxidation, is similar to cooking the gold out, according to Fougerouse. But thi...
