2016-5-27 · I'm hoping our HEPP process can either eliminate or significantly reduce the roasting step (12-18 hours at 600-700 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.
