Roasting (metallurgy)

Roasted gold ore from Cripple Creek, Colorado.Roasting has driven off the tellurium from the original calaverite, leaving behind vesicular blebs of native gold. Roasting is a process of heating a sulphide ore to a high temperature in presence of air. It is a step of the ...This focuses on economic savings (ore resource efficiency) as well as environmental and sustainability benefits (eco-efficiency). “Thus, we consider alternative processes and practices. But every ore body and mining operation is different, so we need to tailor the solutions to suit.
