The invention discloses a preparation method of magnetic cobalt particles, and belongs to the technical field of inorganic material preparation. The preparation method comprises the following steps that (1) cobalt salt, caustic alkali, a complexing agent, a reducing agent and a surfactant are added into ethylene glycol, and uniformly stirring and mixing are carried out to obtain a mixed solution A; and (2) the mixed solution A is transferred into a reaction kettle for solvothermal reaction, and after the reaction is finished, solid substances are separated, washed and dried to obtain the magnetic cobalt particles. According to the preparation method of the magnetic cobalt particles, the magnetic cobalt particles with sea urchin-shaped and porous morphology are prepared in one step through a solvothermal method, and a product is stable in morphology and high in purity; and moreover, required equipment is simple, the preparation process is simple, the production cost is low, and the preparation method is enviro
