|Abstract:||Basic data on leaching of magnesite (MgCO3) with sulphuric acid are of interest from the point of view of the industrial process for obtaining pure MgSO4. The Taguchi method was used to determine the optimum conditions for the dissolution of magnesite in H2SO4 solutions. The experiments were performed within the ranges mentioned herein i.e. 20-65°C for reaction temperature, 0.5/100-10/100 g/mL for solid-to-liquid ratio, 0.2-5 M for acid concentration, 5-60 min for reaction time and 150-750 rpm for stirring speed. The optimum conditions for these factors were found to be 65°C, 5/100 g/mL, 2 M, 60 min and 300 rpm, respectively. Under these conditions, the dissolution mass fraction of MgCO3 in H2SO4 solutions were w = 96.32%.|
