【 摘 要 】

The metallurgical industry is experiencing major issues which are not related to a crisis of the raw materials and energy resources, but to the stringent requirements for the environmental protection. The small-sized and pulverous wastes, stemming mainly from the steel industry but also from the mining industry, respectively the energy industry, due to their high content of iron, manganese, carbon and various oxides, should be named by-products and be deemed as constituents of natural capital, because they can be capitalized in the steel industry. The optimization of the steelmaking process can have radically different approaches, depending on the specific conditions of a steel plant during a specific period of time. The production of steel is continuously increasing worldwide, due to the development of the machinery industries. The steel manufacturers use furnaces that produce steel form various ferrous wastes, instead of traditional raw materials, because the method is effective, given that it assumes low costs.
