FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Method of processing magnesium-containing feedstock is characterized by the fact that finely ground brucite or brucite dressing wastes are treated with 70–96 % solution of sulphuric acid at room temperature and mixed at ratio between sulphuric acid and magnesium-containing raw material (1–4):1 until complete neutralization of sulphuric acid with subsequent grinding of obtained product.
EFFECT: invention widens the range of methods for producing mineral fertilizers.
