The invention discloses a method for promoting reselection in tin polymetallic sulfide ore beneficiation, and relates to the technical field of tin ore beneficiation. Preparing barium chloride and sodium carbonate into solutions with the concentration ranges of 1%-3% and 5%-10% respectively; the cassiterite ore pulp to be separated after flotation desulfurization is introduced into a first stirring barrel, a prepared barium chloride solution is added, the stirring speed is 450 r/min to 600 r/min, and the stirring time is 10 min to 15 min; the ore pulp acted with the agent is introduced into a second stirring barrel, a prepared sodium carbonate solution is added, the stirring speed is 300 r/min to 400 r/min, and the stirring time is 5 min to 10 min; and the ore pulp is subjected to reselection operation, and finally tin concentrate is obtained. According to the method, the to-be-separated cassiterite ore pulp subjected to desulfurization sufficiently acts with the barium chloride solution and the sodium carbon
