چکیده
The article presents the results of a study processes obtaining magnesium oxide by fusing serpentinites Arvaten deposit in presence ammonium sulfate, followed grinding and treatment with water to separate silica from suspension, neutralizing filtrate ammonia pH 8.5 for precipitation separation impurity metal ions, ions solution using carbonate, thermal decomposition corbanate obtain oxide. It has been established that use sulfate fusion serpentite at ratio serpentenite: (NH4)2SO4 = 100: 201.77 further processing resulting solutions allows you composition (wt.%): MgO - 97.55; Fe2O3 0.86; A12O3 0.12; CaO 0.18; SO3 0.48.
