Zusammenfassung:The invention discloses a method for preparing high-purity homogeneous bauxite clinker by utilizing Guyana bauxite. The method comprises the steps: carrying out light burning dehydration on crude Guyana bauxite at the temperature of 800-1000 DEG C, and then carrying out ball milling homogenization to obtain a bauxite light burning material with required mesh number; molding the bauxite lightly-roasted material fine powder with the size of less than 180 mesh into a green brick by a brick pressing method, carrying out heat preservation at the temperature of 1700-1750 DEG C for 3-6 hours, and sintering to obtain a high-purity homogeneous bauxite clinker; and molding the bauxite light burning material micro powder with the particle size of less than 2000 mesh into a biscuit through a ball pressing method or a ball rolling method, carrying out heat preservation at 1700-1750 DEG C for 1-3 hours, and sintering to obtain the high-purity homogeneous bauxite clinker. The maximum particle size of the high-purity homogen
