Process to Recover Gold from Sulfide Ores

May 27, 2016 · I'm hoping our HEPP process can either eliminate or significantly reduce the roasting step (1218 hours at 600700 degrees C), which is currently required for the recovery of precious metals from sulfide laden ores. If so, our process consumes a fraction (4 cents per ton) of the energy of roasting. Quote.
