Thermodynamics, Kinetics, and Key Parameter Optimization of Manganese Extraction from Steel Slag by Indirect Intensification Process of Chlorination Roasting Method

This study utilized the magnetic separation of steel tailings as raw material, employing ammonium chloride as the chlorinating agent to extract valuable manganese elements from steel slag through chlorination roasting. Initially, the feasibility of manganese extraction from steel slag via chlorination was analyzed based on thermodynamic calculations. Subsequently, single-factor experiments, in conjunction with the Plackett-Burman method, were conducted to investigate the effects of roasting temp
