The global transition to a circular economy calls for research and development on
technologies facilitating sustainable resource recovery from wastes and by-products. Metal …

The state of the art for the recovery of metals from steel industry by-products using
hydrometallurgical processes is reviewed. The steel by-products are different slags, dusts …

Iron tailings is the most common and largest mining waste, and given the serious social,
economic, and environmental impacts caused by tailings, green and safe technologies are …

The increasing demand of different essential metals as a consequence of the development
of new technologies, especially in the so called “low carbon technologies” require the …

Solid metalliferous wastes (sludges, dusts, residues, slags, red mud and tailing wastes)
originating from ferrous and non-ferrous metallurgical industries are a serious environmental …

The generation of 300–500 kg of slag per ton of the steel produced is a formidable amount
of solid waste available for treatment. They usually contain considerable quantities of …

Metallurgical slags are generated as a by-product of smelting during ironmaking,
steelmaking, and the production of ferroalloys and non-ferrous metals. The formation …

Metallurgical dusts are by-products from steel manufacturing. The high iron content of cast
house dust (~ 64%) makes this by-product an interesting iron feedstock alternative …

Slags are a by-product in extractive pyrometallurgical operations that have been considered
as an environmental contaminant, an inert material, and a valuable resource. Historically …

The generation of currently partially recyclable metallurgical dusts during the steel
production represents a challenge for the realization of a circular economy in this industrial …
