Environmental Romanian national regulations, harmonized with European legislation,
have imposed a new approach for solving the problems of wastes resulted from
integrated steel mill plant. For the materials that have been historically disposed into a
dump is imposed to find eco-efficient solutions to mitigate the environmental impact of waste and to them eliminating. Finally is possible to rehabilitate the landscape. An
ecological management of these wastes may rely on opportunity to sort these materials and to recover them in function with their characteristics. The fractions of metallurgical slag as valuable iron units can be recycled in the sintering process as materials input for obtaining the ferrous agglomerate. The paper presents the properties of iron-containing materials that will be recycled in the sintering process. This recovered fraction was analysed by microscopy to establish the phase composition. Also the physical and chemical analyses were performed. The properties of valuable materials and its structural phases were discussed in relation with the quality of sintering product and the optimal operation of sintering machine.

Keywords: dump, iron-rich slag, recovery, sintering process
