Beneficiation method for high-argillization fluorite ore with complex dissemination relation

The invention relates to a beneficiation method for high-argillization fluorite ore with a complex dissemination relation. The beneficiation method comprises the following steps: (1) crushing high-argillization fluorite raw ore, and wet-grinding the crushed high-argillization fluorite raw ore until the high-argillization fluorite raw ore accounts for 60-75% of an ore grinding product with the fineness of-0.074 mm; (2) settling and grading the ore grinding product to respectively obtain a fine-grained product with the particle size of less than 0.01 mmd and a coarse-grained product with the particle size of more than 0.01 mm; (3) carrying out roughing and scavenging on the coarse fraction product after size mixing to respectively obtain fluorite rough concentrate, scavenged middling and tailings; returning scavenged middlings to roughing operation; (4) enabling the fluorite rough concentrate to be subjected to size mixing and then subjected to ore grinding, and obtaining reground rough concentrate with the fin
