To provide a method for supplying copper smelting raw materials capable of stably operating by suppressing thermal load fluctuation of a self-fluxing furnace due to charging of miscellaneous raw materials.SOLUTION: A method of supplying copper concentrate, silicate cooling material, and miscellaneous raw materials as copper smelting raw materials to a self-melting furnace 6, of the two bins 1 and 2 provided above a belt conveyor 3 running toward the self-melting furnace 6, from the first bin 1, the copper concentrate is cut out, and from the second bin 2, the silicate-containing cold charge and the miscellaneous raw materials are cut out, and based on the calorific value at the time of combustion in the self-melting furnace 6 of the copper concentrate cut from the first bin 1, a cut out amount from the second bin 2 is controlled.SELECTED DRAWING: Figure 2 【課題】 雑原料の装入に起因する自熔炉の熱負荷変動を抑制して安定的に操業することが可能な銅製錬原料の供給方法を提供する。【解決手段】 銅製錬原料としての銅精鉱、含珪酸塩冷材、及び雑原料を自熔炉６に供給する方法であって、自熔炉６に向かって走行するベルトコンベア３の上方に設けた２基のビン１、２のうち、第１のビン１から銅精鉱を切り出すと共に第２のビン２から含珪酸塩冷材及び前記雑原料を切り出し、第１のビン１から切り出した銅精鉱の自熔炉６での燃焼時の発熱量に基づいて第２のビン２からの切り出し量を制御する。【選択図】 図２
