The invention relates to the technical field of copper-molybdenum ore beneficiation, and discloses a beneficiation method suitable for copper-molybdenum ore with different ore supply grades, two storage systems are adopted for storing high-grade supplied ore and low-grade supplied ore respectively, the high-grade supplied ore is fed into a high-grade flotation system after being subjected to primary ore grinding, and the low-grade supplied ore is fed into a low-grade flotation system after being subjected to secondary ore grinding; high-grade copper-molybdenum concentrate is obtained through roughing, scavenging, concentration and the like; the low-grade supplied ore is fed into a high-grade flotation system after being subjected to multiple times of ore grinding, and low-grade copper-molybdenum concentrate is obtained through roughing, scavenging, concentration and other operations; and the high-grade copper-molybdenum concentrate and the low-grade copper-molybdenum concentrate are mixed and then subjected t
