The recovery of gold from refractory ores has also steadily increased over the past 20 years, largely a result of circumstance and necessity, as the easier free-milling gold ores have been depleted. In turn, hydrometallurgical processes, like pressure-oxidative and bacterial leaching, have in many cases superseded traditional roasting practice.
