Summary:The invention relates to an innocent treatment method for arsenic containing mixed salt. The method comprises the following steps of: (1) uniformly mixing arsenic containing mixed salt and slag or/and cullet, and controlling the content of arsenic in the mixed material at1.0-4.8wt% to obtain a mixed material; (2) feeding the mixed material into a furnace, heating to 1150-1250 DEG C, and insulating and melting for 0.4-2.4 hours to obtain melt; and (3) pouring the melt to a die to prepare solid or entering into water for water-quenching while the melt is still hot to obtain particle arsenic containing solid. The method for treating the arsenic containing mixed salt is free from environmental hidden danger, and free from secondary pollution, and the whole process is simple in flow, short in processing time, simple and convenient to operate, low in energy consumption, and suitable for industrialized production.
