The invention relates to a multi-metal coupling activation flotation method for high-calcium siliceous zinc oxide ore, and belongs to the technical field of mineral processing. In order to solve the technical problems of poor selectivity, weak collecting capacity, unsatisfactory separation indexes and the like when a traditional flotation reagent is adopted for the high-calcium siliceous zinc oxide ore, after the high-calcium siliceous zinc oxide ore is subjected to crushing, ore grinding and size mixing, a composite regulator is added to selectively inhibit gangue minerals, and surface modification is conducted on the zinc oxide minerals; adding a coupling activator to deeply activate the modified zinc oxide mineral to enhance the reaction activity of the mineral surface, adding a composite vulcanizing agent after activation to act on the mineral surface to generate a high-activity vulcanized surface, and adding the coupling activator after vulcanization to form a multi-metal sulfide coupling activation inte
