It uses a two-stage acid leach with short, one-hour acid residency times in which the acid is a catalyst, and therefore little of the acid is consumed in the reaction. An acid recycling circuit serves to help further minimize costs. The process also completely neutralizes the acid-forming potential of the pyrites in refractory ore.
