METHOD AND SYSTEM FOR PRODUCING POTASSIUM CHLORIDE CAPABLE OF RECYCLING BYPRODUCT

Provided are a method and system for producing potassium chloride that are capable of recycling a byproduct. The system comprises: a raw ore processing system (1), a pulp mixing system (2), a flotation system (3), a low-sodium concentration and dehalogenation system (4), a cold crystallization and crude potassium screening system (5), a crude potassium concentration and dehalogenation system (6), a refined potassium washing and dehalogenation system (7) and an overflow liquid and filtrate processing system (8). The method comprises: a carnallite ore pulp is sequentially processed through the above systems to obtain an overflow liquid, a filtrate, a tail salt and a potassium chloride product, etc. in each stage. The system and method increase the yield of potassium chloride and save on costs. L'invention concerne un procédé et un système de production de chlorure de potassium qui sont aptes à recycler un sous-produit. Le système comprend : un système de traitement de minerai brut (1), un système de mélange de
