Disclosed is a method for producing a carbonaceous material-containing pellet that has high strength and can increase the reduction rate and improve the efficiency of a blast furnace process despite the high carbonaceous material content. Carbonaceous material-containing pellets are produced by a granulating process of pellet raw materials containing fine iron ore and / or dust with 5 parts by weight or more of carbonaceous material as an essential component with respect to 100 parts by weight of the pellet raw material. It is a method, Comprising: The said granulation process process is a carbonaceous material containing pellet granulated in presence of the high molecular compound which has 1 or more types of groups chosen from the group which consists of a carboxyl group, a sulfonic acid group, and these salts. Manufacturing method. [Selection figure] None |
