May 28, 2019· Since gold foil cannot be oxidized, by itself it should not produce any molecular oxygen. But when carbon dioxide careens into the foil at high speed, the gold surface emits molecular oxygen.
Gold-containing ores, having refractory sulfidic matter or a combination of refractory sulfidic matter and refractory carbonaceous matter, are processed to recover their gold values. The process uses an ore roasting procedure that utilizes a two-state, fluidized bed roaster. The process also employs a pure oxygen atmosphere during roasting.
