Description

Technical Field

[0001] The utility model relates to the technical field of refined gold ore roasting, and specifically to a device for treating tail gas from refined gold ore roasting. Background Art

[0002] The roasting oxidation method in the roasting of gold concentrate is a pyrometallurgical pretreatment method for difficult-to-smelt ores, especially those with high sulfur and arsenic content. During roasting, components such as As, S, and Sb in the ore are oxidized and transferred to the gas phase, producing a loose oxide roasted sand suitable for cyanide gold extraction. This dissociates or exposes microscopic and submicroscopic particles of encapsulated gold from sulfide and telluride minerals, producing a porous roasted sand that facilitates contact between the cyanide leaching solution and the gold, thereby improving gold recovery. The activated carbon is oxidized or passivated during roasting, losing its activity.
