The invention relates to a method for producing low iron aluminum sulfate by the utilization of coal gangue and belongs to the technical field of coal solid waste resource utilization. The method provided by the invention comprises the following steps of: carrying out calcination activation on coal gangue at the temperature of 785-850 DEG C, adjusting the pH of an aluminum sulfate solution by directly using the activated coal gangue, oxidizing divalent iron ions into trivalent ions, removing iron precipitate and a few gel in the aluminum sulfate solution by the utilization of the adsorption property of the coal gangue, producing low iron aluminum sulfate, recycling the removed iron slag, and terminating the recycling operation when the removed iron slag amount is greater than 120% of the acid-leach residue amount or the mass ratio of aluminium to iron in an iron-removing liquid is less than 160. The temperature of the calcinated coal gangue satisfies the operation condition for the boiling of a circulating fluidized bed. No addition of an auxiliary agent helps heat recovery. The activity of the coal gangue cinder is good, the grinding requirement is not high and the energy consumption is low. Hydrogen peroxide or ozone, air and variable valence element-containing hypervalent compounds KMnO4, MnO2 oxidizing agents are adopted to remove iron with less loss of aluminium. The ratio of Al2O3 to Fe in the product is greater than 160 and the quality of the product is high. The acid leaching reaction is carried out at normal pressure. And the production is easy to operate at low cost.
