Reductive thermal plasma conversion of a spodumene concentrate and impact on lithium extraction

•Spodumene conversion was performed using a reductive CO2/CH4 thermal plasma gas.•γ-spodumene negatively impacts lithium extraction efficiency and must be managed.•Two reactor configurations were studied, a Spouted Bed (SBR) and Rotary Plasma (RPR)•Coarse particles (up to 2 cm) become micrometric (...
