Steelmaking slags treated with aqueous H2SO4 were characterized as Se(IV) adsorbents, and notable adsorption ability was shown to develop at concentrations of 0.18–0.20 mol/L. The enhanced performance sulfated in the presence H2O2 suggested that their sites contained Fe(III) resembled those schwertmannite. Langmuir analysis isotherms used determine corresponding capacities constants. Thus, obta...

The project SUBproducts4LIFE is a LIFE-funded research that aims to demonstrate innovative circular economy concepts by repurposing industrial subproducts/waste (coal ash and gypsum from coal power plants, blast furnace slag, steelmaking slag steel factories) for the remediation of contaminated soils brownfield areas associated with Hg mining on large scale. Within project, one objectives relat...

Hydrogen-based direct reduction is a promising technology for CO2 lean steelmaking. The electric arc furnace the most relevant aggregate processing reduced iron (DRI). As DRI usually added into arc, behavior in this area of great interest. A laboratory-scale hydrogen plasma smelting (HPSR) reactor was used to analyze that under inert conditions. Four cases were compared: carbon-free and carbon-...

In the present work, dephosphorization experiments by using new double slag converter steelmaking process (NDSP) has been carried out in a 180 ton top-bottom combined blowing under low temperature range of 1345–1450°C and basicity about 1.50. With increasing endpoint temperature, ratio, P2O5 content phosphorus distribution ratio logLP first increase then decrease. The apparent equilibrium const...
