Symposium Advances in Recycling and Environmental Technologies
Presentation Title Advancing Non-Ferrous Smelting with Coherent Jet Technologies: Oxyfuel-Based Optimization of TSL and TBRC Processes for E-Scrap and Metal Recycling

On-Site Speaker (Planned) Brenno Ferreira
Abstract Scope This paper explores the transformative role of Coherent Jet (CoJet) technologies in modernizing Top Submerged Lance (TSL) and Top Blow Rotary Converter (TBRC) systems for non-ferrous recycling and smelting applications. With conventional air and enriched-air lances being replaced by 100% oxyfuel burners—including hydrogen-enabled variants—these systems facilitate enhanced heating, stirring, and reduction mechanisms across copper, lead, and E-scrap processing. The deployment of CoJet solutions unlocks significant gains in metal recovery efficiency, operational productivity, and scope 1 carbon footprint reduction. Performance metrics are evaluated through thermal modeling, fluid dynamics, and energy balances, showcasing the benefits of high-intensity jet interaction and tailored combustion profiles. Ultimately, CoJet represents a key enabler for sustainable metallurgical practices within the circular economy, aligning decarbonization objectives with production targets in high-temperature non-ferrous operations.
