Outlined here are our strategies for enhancing residue management in steel production, focusing on innovative separation, treatment technologies, and sustainable recycling practices.
- Physical, chemical and mineralogical characterization of residues samples from steel production for selection of treatment method
- Development of technologies, with relatively low starting TRL, for separation and treatment of low-zinc residues from steel plants.
– Hydrocyclone pilot prototype will be designed using CFD modelling and simulation, followed by construction and experimental testing with residues from BF and BOF
– Internal recycling of EAF-dust and biochar briquettes
– Development of pyrometallurgical treatment methods, e.g. design, operational parameters, feed material properties with Oxyfines technology, rotary heart furnaces and rotary kilns.
– Zinc enriched fractions can be recovered at zinc smelters or further processed by hydrometallurgical treatment. - Design the most sustainable recycling routes for different residues regarding environmental impact, energy consumption and CO2 emissions, as well as cost-effectiveness.
