The invention provides an antimony ingot feeding method of antimony smelting. An antimony ingot temperature-resistant material collection hopper is installed on an antimony metallurgical furnace. Antimony ingots are arranged in the temperature-resistant material collection hopper, move downwards in the temperature-resistant material collection hopper under the effect of gravity, and fall on a heated material melting table arranged at the bottom of the interior of the furnace. Melt in the furnace slowly melts the bulk antimony ingots, and molten antimony liquid flows downwards to effectively supplement molten liquid in the furnace so that the molten liquid can be kept at a certain liquid level for a long time. By means of the antimony ingot feeding method of antimony smelting, raw materials do not need to be input regularly and quantitatively in the production process; and in this way, the labor intensity of operators can be lowered, and meanwhile the production efficiency can be improved. In addition, it can be avoided that because excessively-large furnace temperature fluctuation is caused by human factors in the production process and especially workshop environments are influenced by high-temperature melt splashing, smoking and the like when workers conduct throwing, the production condition in the furnace is not stable and the product quality is influenced.
