Optimization of Magnesium Separation and Extraction from Boron Slurry Using Response Surface Methodology

Abstract:

Response surface methodology was used to optimize the soaking Mg leaching ratio from the boron slurry screened by 2⁵ fractional factorial design. Five effective factors such as H₂SO₄ concentrations, reaction time, reaction temperature and stir velocity were tested by using 2⁵ fractional factorial design criterion and three effective factors H₂SO₄ concentrations, reaction time and reaction temperature showed significant effect(P2SO₄ concentrations of 0.29mol/l, reaction time of 90 min and reaction temperature of 50°C. Three runs of additional confirmation experiments were conducted. The mixture magnesium leaching value was 58.20%.
