Zusammenfassung:Based on the theoretical analysis and experimental tests of dearsenation of gold-bearing arsenopyrite ore in water steam atmosphere, the authors show that during bakeout of arsenopyrite with pyrite in the superheated water steam atmosphere, it is possible to remove arsenic in the form of sulfides and unlock noble metals.
