Disclosed is a method for smelting magnesium from dolomite by vacuum carbothermal reduction. The method includes: pressing a mixed powder of dolomite and coking coal to obtain a block; and heating the block directly to obtain a heated block, subjecting the heated block to a carbothermal reduction reaction in vacuum to obtain a reduced vapor, and condensing the reduced vapor to obtain crystalline magnesium, wherein the heating is conducted at a heating rate of ≤12 K/min; and the carbothermal reduction reaction is held at a temperature of ≥1,400 K for ≤2 h.
