The invention provides a method for comprehensively utilizing high alumina iron ore. The method comprises the steps that an additive and composite binding agent are added to preprocessed high aluminairon ore, and mixing, pelletizing and drying are conducted to obtain high alumina iron ore dry pellets; dry pellets are oxidized, roasted and solidified at 1050-1300 DEG C to obtain oxidized pellets;a reducing agent is added to the oxidized pellets to conduct pre-reduction treatment to obtain pre-reduced pellets; the reducing agent is added to the pre-reduced pellets, and electric furnace meltingtreatment is conducted after mixing to obtain pig iron and melting slags; the melting slags and the additive are mixed and modified to obtain modified slags; ball milling and alkali leaching are conducted on the modified slags to obtain silicon enriched slags and an aluminate solution. The method has the advantages that the iron recovery rate is high, the separation of iron, aluminum and siliconcan be achieved, the energy consumption is low, silicon tailing slags can be applied to preparing building materials, the generation of secondary solid wastes is prevented, environmental pollution isnot generated, and industrial production is easily achieved.
