Development the Steel Industry Waste-free by Internal Recycling of the Blast Furnace Dusts

The development of steel industry is subject to solve major problems strictly targeted on pollution control and protection of natural resources and energy. The development strategies of steel integrated works around the world have two directions: development of the advanced technologies in respect to the substantially decreasing emissions and increasing the recycling ratio of the wastes and by-products. In this paper a solution is analyzed for integrated management of blast furnace dusts in accordance with their essential quantification (quantitative, qualitative and the generation sources) and transformation of these wastes into valuable by-products used directly by the company in an internal process. The physico-chemical properties that are relevant for recycling solution are discussed as respect to the optimum valorization. Also, the morphology and mineralogy of these dusts are presented in accordance with fundamental aspects of its generation process.
