ZHYRON

Implementation of highly efficient technologies for the recovery of metals (iron and non-ferrous metals) and mineral fractions from in-plant steelmaking residues. The recovery technology should condition the composition and properties of the residue, such as, among others, slag, sludge, scale, filter dust, sintering residues produced by the blast furnace / basic oxygen furnace (BF / BOF) and electric arc furnace (EAF) routes, but also by the next generation iron and steel making, such as, among others, the direct reduction / electric arc furnace (DR / EAF) route, including the melting and reduction of low-grade iron ore.

Two possible ways are envisaged: the first is based on mechanical and cooling steps, such as, among others, wet or dry granulation followed by phase separation; the second is based on dedicated processes to allow a direct recycling of residues in existing production processes or in stand-alone pyrometallurgical or hydrometallurgical / biohydrometallurgical smelting and reduction units. 

This knowledge and results should support the valorization of waste in the current value chain and/or in innovative applications. If appropriate, the wastes could be characterized chemically and structurally at the micro-scale level through characterization (also multimodal) performed in analytical research infrastructures, which would allow obtaining relevant statistical information.

Describe and/or modify the composition and properties of wastes such as, but not limited to, slags and/or sludges produced by next generation steelmaking, such as, but not limited to, the DR / EAF pathway.
