A solid bleach-fixing composition for a silver halide color photographic light-sensitive material, comprising at least one specific 5-membered heterocyclic azoliumthiolate compound, particularly, a solid bleach-fixing composition wherein the specific thiolate compound is a diazolium-thiolate compound substituted by a water-soluble group. A method for processing a silver halide color photographic light-sensitive material, comprising using a bleach-fixing solution containing a specific 5-membered heterocyclic azoliumthiolate compound, and regenerating at least 50 mass % of the used bleach-fixing solution as a bleach-fixing processing agent for replenishment; and a method for processing a silver halide color photographic light-sensitive material, comprising regenerating at least 30 mass % of the used processing solution further containing used rinsing solution as a bleach-fixing processing agent for replenishment.
