Process method for recovering gold and silver from high-arsenic gold concentrate through desulfurization and arsenic removal

The invention discloses a process method for recovering gold and silver from high-arsenic gold concentrate through desulfurization and arsenic removal, and relates to the field of hydrometallurgy. According to the process method for recovering gold and silver from high-arsenic gold concentrate through desulfurization and arsenic removal, the original two-section roasting system is subjected to technical transformation, so that the original equipment is utilized, and the capital investment is reduced; the ore feeding amount of an original 200 t/d roasting system is about 180 t/d, and the ore feeding amount can reach 240-250 t/d after transformation; and the comprehensive recovery rate of roasting slag directly entering pyrometallurgy gold can reach 95% or above, the economic benefit is considerable, the competitive advantage in the aspect of raw material purchasing is expanded, no waste water or hazardous waste is generated in the process, and the national environmental protection requirement is met. 本发明公开了一种高
