Abstract
The article describes theoretical and experimental data on dearsenation of gold-containing scorodite ore in water vapor. It is shown that roasting of scorodite with pyrite in super-heated vapor enables complete removal of arsenic and sulfur in the form of sulfides of the original material and exposes noble metals.
