The invention discloses a method for producing high-iron low-calcium clinker and belongs to the technical field of building materials. The method comprises the following steps: by taking 78-83% of limestone, 12-16% of sandstone, 3-6% of nonferrous metal ash and 0.3-0.8% of a composite additive consisting of CaF2, CuO, P2O5 and Zn as raw materials, performing powdering, preparing cakes, crushing the cakes, further performing calcining so as to obtain clinker, and finally cooling and crushing the clinker, so as to obtain the high-iron low-calcium clinker. The method is low in raw material cost,and the prepared high-iron low-calcium clinker is high in strength, low in hydration heat and applicable to engineering or parts with special requirements.
