Изобретение относится к металлургии, в частности к области подготовки руд к плавке методом агломерации, и может быть применено на агломерационных фабриках цветной металлургии, например, при агломерации окисленной никелевой руды. Способ производства агломерата с повышенным содержанием остаточного углерода включает подготовку твердого топлива и руды, смешивание и спекание. При этом верхний предел крупности используемого топлива определяется из фракционного состава рудной части шихты по соотношению: dт = 0,3dр, где dт - верхний предел крупности топлива, мм; dр - верхний предел крупности руды, мм; причем, содержание фракции, соответствующей верхнему пределу крупности топлива, составляет не более 10% массы топлива. Предлагаемый способ позволяет увеличить содержание остаточного углерода в агломерате до 2,3 - 3,0% без увеличения расхода топлива на агломерацию сверх необходимого для спекания, а также снижает выбросы окиси углерода с отходящими газами агломерации в атмосферу.The invention relates to metallurgy, in particular to the field of preparation of ores for smelting by the agglomeration method, and can be applied at non-ferrous metallurgy sintering plants, for example, during the agglomeration of oxidized nickel ore. A method for the production of agglomerate with a high content of residual carbon includes the preparation of solid fuel and ore, mixing and sintering. In this case, the upper limit of the fineness of the fuel used is determined from the fractional composition of the ore part of the charge by the ratio: d t = 0.3d p , where d t is the upper limit of the fineness of the fuel, mm; d p - the upper limit of ore fineness, mm; moreover, the content of the fraction corresponding to the upper limit of the fineness of the fuel is not more than 10% of the mass of fuel. The proposed method allows to increase the residual carbon content in the agglomerate to 2.3 - 3.0% without increasing the fuel consumption for agglomeration in excess of the necessary for sintering, and also reduces emissions of carbon monoxide from the agglomeration exhaust gases into the atmosphere.
