Abstract

The Taguchi method was used to determine the optimum conditions for the dissolution of ulexite in ammonium sulphate solutions. The ranges of experimental parameters were between 60-88°C for reaction temperature, 0.05-0.15 g.mL-1 for solid to liquid ratio, 5-20 minutes, for reaction time and (-850+600) - (-90) μm for particle size. The optimum conditions for these parameters were found to be 88°C, 0.1 g.mL -1, -90 μm and 20 minutes, respectively. Under these conditions, the predicted and experimental dissolution percentages of ulexite in ammonium sulphate solutions were 98.60 and 98.36 per cent, respectively. © Canadian Institute of Mining, Metallurgy and Petroleum.
