The invention provides a method for reinforcing leaching of bornite through high-iron sphalerite. The method includes the following steps that the high-iron sphalerite and the bornite are ground, andhigh-iron sphalerite powder and bornite powder are obtained; a 9K basic culture medium is subjected to high-temperature high-pressure steam sterilization, and the high-iron sphalerite powder and the bornite powder are intermittently sterilized; the sterilized high-iron sphalerite powder and the sterilized bornite powder are mixed, then the sterilized 9K basic culture medium is added, ore pulp is obtained, and then the pH value of the ore pulp is adjusted to 1.5-2.0; and the ore pulp is subjected to agitation leaching, and chemical conditions of a leaching solution are adjusted and controlled.The whole leaching period is shortened, meanwhile, the leaching rate and the leaching speed are greatly increased, and the method is clean and environmentally friendly, low in cost and suitable for large-scale application and popularization.
