Abstract

This study specifically addresses the challenges in chromium extraction during the calcium-free roasting process of chromite ore. It meticulously examined how key process parameters-including roasting temperature, roasting time, oxygen concentration and atmosphere, alkali dosage, and material particle size-afect the final extraction efficiency. Through continuous optimization of these parameters, experimental results clearly demonstrate that strict control of critical conditions significantly enhances chromium extraction rates while effectively reducing energy consumption and minimizing environmental impact. This extraction method improves chromium resource utilization efficiency, advances the goal of more environmentally sustainable metallurgical processes, and provides crucial technical support with broad future applicability. The experimental data unequivocally highlight the method’s numerous advantages and outstanding value.
