In the present research, the influence of pH and dose of aluminum hydroxide on the sulphates removal percentage present in artificial mine water, by means of mineral precipitation treatment was evaluated. For the research, the artificial mine water was prepared, utilizing supplies chemical grade (99%) of CuSO4, K2SO4, MgSO4, Na2SO4, FeCl3.6H2O and MnSO4 in amounts of 5.00, 4.00, 3.00, 1.50, 0.30 and 0.20 g of each reactant, dissolved in 5.00 L of distilled water, to obtain a final chemical composition of 1740, 400, 360, 120, 100, 24, 14 and 12 ppm of SO4 2-, Cu2+, K+, Mg2+, Na+, Cl-, Mn2+ and Fe2+ respectively, with a pH 3.60 as initial parameters, that are physicochemical characteristics similar to acid mine drainage (AMD) studied by Geldenhuys (2003) and Cadorin (2007), which served as model for this study. The research has utilized precipitation reactions during successive stages for ...
