This paper examines the theoretical foundations for producing organomineral potassium fertilizer by converting
potassium chloride with spent sulfuric acid followed by ammoniation. Based on the analysis of the reciprocal system 2K⁺,
2NH₄⁺ // 2Cl⁻, SO₄²⁻ – H₂O, polythermal solubility diagrams were constructed and crystallization regions were determined.
The choice of process mode is governed by the figurative point position and component ratio. A comparative analysis of
two processing options was performed, and the optimal conditions for K₂SO₄ production were established. The second
option provides a maximum K₂SO₄ yield of up to 87.04 % and is technologically preferable
