To provide a method for producing carbonaceous material-containing particles, in which, in a course of being conveyed to a sintering machine and being charged into the sintering machine, collapse of carbonaceous material-containing particles can be suppressed.SOLUTION: Provided is a method for producing carbonaceous material-containing particles, in which a powdery iron-containing raw material, a lime-containing raw material, at least one of an organic binder and bentonite, and a cement powder are mixed to form a mixed powder, and the mixed powder and a carbonaceous material are granulated to produce carbonaceous material-containing particles in which an outer layer made of the mixed powder is formed around the carbonaceous material core.SELECTED DRAWING: Figure 1 【課題】焼結機へ搬送され、焼結機に装入される工程において炭材内装粒子の崩壊を抑制できる炭材内装粒子の製造方法を提供する。【解決手段】炭材内装粒子の製造方法であって、粉状の鉄含有原料と、石灰含有原料と、有機バインダーおよびベントナイトのうち少なくとも１種と、セメント粉と、を混合して混合粉とし、混合粉と、炭材とを造粒して、炭材核の周囲に混合粉からなる外層が形成された炭材内装粒子を製造する。【選択図】図１
