The invention discloses a basalt beneficiation method which is characterized by comprising the following steps: taking basalt raw ore, crushing the basalt raw ore into coarse ore with the particle size of less than or equal to 3mm through a crusher, and grinding the coarse ore through an ore grinding machine to obtain basalt raw ore powder; feeding the basalt raw ore powder into a magnetic separator for first-stage low-intensity magnetic separation to obtain first-stage low-intensity magnetic separation magnetic components and first-stage low-intensity magnetic separation middlings; feeding the first-stage low-intensity magnetic separation middlings into a magnetic separator to be subjected to high-intensity magnetic separation, and obtaining second-stage high-intensity magnetic separationmagnetic components and second-stage high-intensity magnetic separation non-magnetic components; and combining the first-stage low-intensity magnetic separation magnetic component and the second-stage high-intensity magnetic
