METHOD AND SYSTEM FOR PRODUCING POTASSIUM CHLORIDE CAPABLE OF RECYCLING BYPRODUCT

WIPO Patent Application WO/2020/177159

A1

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.
