Despite a lot of studies of iron ore raw materials was carried out both in sinter and BF production areas, the matter of agglomeration burdens optimization is still actual. Laboratory studies on sintering of agglomeration burdens of different component content were carried out for optimization of iron ore burden content optimization, following by determination of technology characteristics and metallurgical properties complex.As a result of the studies an optimal component and size content of the agglomeration burden determined to provide improving of metallurgical properties complex of agglomeration burden. The studies carried out showed, that lime introducing into the concentrate flow before the burden department can lead to sintering machines productivity increasing.The burden wetness range determined, enabling for complete lime hydrating. It was shown, that a partial replacement of agglomeration ores in the burden by BOF nickel slag contributes to agglomeration process specific productivity increasing as well as sinter strength increasing.
