The invention relates to a method for decyanation treatment of cyanidation tailings and a decyanation agent composition. The decyanation agent composition comprises inorganic metal salt, a flocculating agent and a catalyst. Based on the total weight of the decyanation agent composition, the content of the inorganic metal salt is 20-80% by weight, the content of the flocculant is 5-10% by weight, and the content of the catalyst is 5-20% by weight. When the decyanation agent composition is used for decyanation treatment of cyanogen-containing tailings, the applicability of the reaction can be improved, ventilation and aeration are not needed, and the operation difficulty can be reduced; meanwhile, the decyanation pharmaceutical composition has a good synergistic effect, the cyanide removal rate and the decyanation rate can be increased, and the cost can be reduced. 本公开涉及一种氰化尾矿脱氰处理的方法及脱氰药剂组合物，所述脱氰药剂组合物包括无机金属盐、絮凝剂和催化剂；以所述脱氰药剂组合物的总重量为基准，所述无机金属盐的含量为20～80重量％，所述絮凝剂的含量为5～10重量％，所述催化剂的含量为5～20重量％。采用本公开的脱氰药剂组合物对含氰尾矿进行脱氰处理
