摘要：<p>Disclosed is an unfired carbon-containing agglomerate that has a carbon content (T.C) in the range of 18 to 25 mass%, and a CaO/SiO2 ratio of CaO content (mass%) and SiO2 content (mass%) in the range of 1.0 to 2.0. Also provided is a production method for the unfired carbon-containing agglomerate that is provided with a molded body formation process for obtaining a molded body by mixing and kneading iron-containing materials, carbon-containing materials, and a binder, and molding the kneaded mixture; and a process for obtaining the unfired carbon-containing agglomerate by subsequently curing the aforementioned molded body. In the aforementioned molded body formation process, one or more combination conditions selected from a group comprising the ore type and the combination quantity of the binder are adjusted in a manner such that the carbon content (T.C) of the aforementioned unfired carbon-containing agglomerate becomes in the range of 18 to 25 mass% and the CaO/SiO2 ratio of the CaO content (mass%) and the SiO2 content (mass%) in gangue components becomes in the range of 1.0 to 2.0.</p>
