Abstract Sulfation roasting followed by water leaching has been proposed as an alternative route for recycling valuable metals from spent lithium-ion batteries (LIBs). In the present work, reaction mechanism of sulfation synthetic LiCoO 2 was investigated both thermodynamic calculations and experiments under flowing 10% SO -1% O -89% Ar gas atmosphere at 700°C. The products microstructural evolution processes were characterized x-ray diffraction, scanning electron microscope energy...
Improving metal–slag separation in pyrometallurgical processes is increasingly important. Due to the harsh conditions, direct observations of molten phases behavior settler Outotec Flash Smelting Furnace (FSF) are not possible and ways improve metal settling can only be studied by simulation modeling. This study focuses on kinetics mechanisms chemical reactions between matte droplets slag, which were investigated laboratory-scale heat-quench equipment at a typical smelting temperature 1300°C...
The modelling of different parts Submerged Arc Furnace(SAF) used in ferroalloy production has been investigated and the summary showed that both 2D 3D simulations will help to improve process for ferroalloys production. However, most developed models are lack verification from industry, which needs be studied or improved future. And on electrodes lining SAF is helpful better understanding inside environment furnace hence decreasing breaking electrodes, prolonging lifetime lining. Modelling...
