The invention belongs to the technical field of metallurgy, and in particular, relates to a method for comprehensively treating arsenic-contained smoke and synthesizing arsenic fixing minerals by a control growth method. The method comprises four steps of oxygen pressure water leaching, leaching liquid arsenic fixation, leaching slag washing and recovery of valuable metal from washing slag in sequence; the method uses the oxygen pressure water leaching for removing solvable arsenic in the smoke; arsenic in leaching liquid is synthesized as high-stability arsenic fixing minerals by the control growth method; and then, the arsenic fixing minerals are cured by a stockpiling mode. All valuable elements are recycled from leaching slag to the greatest extent by such procedures as washing, reduction smelting and oxidation blowing. The method removes arsenic from the smoke and synthesizes the stable arsenic fixing minerals, but retains antimony, lead, bismuth and the like in the leaching slag as far as possible, and realizes separation of arsenic from the valuable metal and harmlessness. The method is high in resource comprehensive utilization rate and wide in raw material application range, solves the pollution problem in the traditional extracting process, in particular the smoke generated in the lead-zinc smelting process, and is more obvious in advantages.
