Summary:To provide an operation method for a fusion furnace capable of improving recovery efficiency of useful metal contained in an object to be treated.SOLUTION: An operation method for a fusion furnace comprising a furnace chamber 4 in which an object to be treated containing useful metal is put from an upstream side, and fused slag generated by fusing the object to be treated from a surface by a heating mechanism 8 provided on a furnace ceiling 5 flows down toward a downstream side, and a slag hole 7 that discharges the fused slag having flowed down, comprises: putting base material particles containing a metal component that forms an alloy with useful metal in a fused state into the object to be treated, to aggregate fused metal generated by the fusion process into the base material particles.SELECTED DRAWING: Figure 2 【課題】処理対象物に含まれる有用金属の回収効率を上げることができる溶融炉の運転方法を提供する。【解決手段】有用金属を含む処理対象物が上流側から投入され、炉天井５に備えた加熱機構８により処理対象物を表面から溶融処理して生じた溶融スラグを下流側に流下する炉室４と、流下した溶融スラグを排出する出滓口７と、を備えた溶融炉の運転方法であって、有用金属と溶融状態で合金を形成する金属成分を含有する母材粒子を処理対象物に投入することにより、溶融処理により生じた溶融金属を母材粒子に凝集させる。【選択図】図２
