The invention provides a manufacturing method of a manganese-zinc ferrite small magnetic core, and relates to the field of oxide magnetic materials. The manufacturing method of the manganese-zinc ferrite small magnetic core comprises the following manufacturing steps: S1, formula materials are selected, specifically, raw materials are selected from ferric oxide, manganous-manganic oxide and zinc oxide, and the raw materials comprise 50-58 mol% of ferric oxide, 20-30 mol% of manganous-manganic oxide and 6-13 mol% of zinc oxide; S2, weighing and mixing: the three materials are weighed and selected through an electronic scale according to the weight ratio, the weighed three materials are placed in a cone mixer to be mixed, and after mixing is completed, uniform mixing and fine grinding operation is conducted through a vibration mill. According to the process of the preparation method, the pre-sintering temperature of the magnetic powder is increased to passivate the intensity of a chemical reaction of a blank during secondary sintering and prevent deformation caused by sintering adhesion, so that the percent of pass of the manganese-zinc ferrite small magnetic core is increased to 99.8% from 96%, the energy consumption is reduced by 5%, and the production efficiency is improved by 10%.
