The invention relates to a method for preparing iron-containing pellets in a molten salt electrolytic tank through reduction, and belongs to the technical field of nonferrous metallurgy. The preparation method comprises the following steps: grinding and uniformly mixing alkali metal chloride fused salt, putting into an alumina crucible, and removing moisture in a vacuum drying oven; placing the alumina crucible in an inner container of a resistance furnace filled with inert gas, heating and preserving heat, adding micron-sized Fe2O3 powder, and completely and uniformly mixing with the fused salt to obtain the fused salt; under the condition that inert gas is introduced, a molybdenum net serves as a cathode, a graphite rod serves as an anode, the molybdenum net is immersed in the fused salt, the graphite rod is inserted into the fused salt without touching the bottom, a voltage-stabilized source is communicated with the cathode and the anode, and iron-containing pellets are prepared through ...
