Production of potassium sulphate (SOP)
Fine MOP is a basic raw material to produce potassium sulphate (SOP) using the Mannheim process, where potassium chloride reacts with sulphuric acid at 600-700°C in a muffle furnace. SOP is used in a powder or granular form primarily in agriculture as a chloride-free fertilizer.
Due to its grain size, White Fine MOP produced by Uralkali reacts effectively and completely with sulphuric acid, while the low content of impurities in White Fine MOP ensures production of high purity SOP.
