The method [6] of obtaining magnesium oxide from calcined dolomite, in combination with the production of soda, by treating dolomite milk with a distillation liquid of soda production, consists in separating the solid phase from the resulting suspension, washing the precipitate, repulping it in water, carbonizing the resulting
Magnesium sulfate is an inorganic salt with the formula MgSO 4 (H 2 O) x where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO 4 ·7H 2 O), commonly called Epsom salt.The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority was used in agriculture.
