Abstract
The Based on the theoretical analysis and experimental tests of dearsenation of gold-bearing arsenopyrite or in water steam atmosphere, the author 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 from original material and unlock noble metals.
