Abstract

The purpose of the present invention is to manufacture, without the use of iron oxide powder containing metallic iron, such as iron manufacturing dust or mill scale, a carbon composite sintered ore (carbon composite agglomerated ore) with a two-layer structure in which an iron-containing raw material and a carbon material are disposed adjacently and the periphery of a carbon material core is covered with a mixed powder comprising powder of the iron-containing raw material and powder of a CaO-containing raw material. Provided is a sintered ore manufacturing method in which a carbon composite sintered ore is manufactured by sintering, on a pallet of a sintering machine, carbon composite pelletized particles with a two-layer structure in which a carbon material core is covered with a mixed powder containing a powder of an iron-containing raw material and a powder of a CaO-containing raw material, wherein the water content of the carbon composite pelletized particles at the time of pelletization is 8-10 mass pcnt of the total mass of the carbon material core, the mixed powder, and the water content.
