How to Make Gold in a Flash

ByTim De ChantNOVA NextNOVA Next

Richard A. Lovett, writing for Nature News:

When mineral-laden water at around 390 °C is subjected to that kind of pressure drop, Weatherley says, the liquid rapidly vaporizes and the minerals in the now-supersaturated water crystallize almost instantly — a process that engineers call flash vaporization or flash deposition. The effect, he says, “is sufficiently large that quartz and any of its associated minerals and metals will fall out of solution”.

Including gold, apparently.
