Abstract

The invention provides a method for preparing food-grade potassium chloride by utilizing potassium-containing tail salt. The method comprises the following steps: adding water into the potassium-containing tail salt and decomposing; filtering decomposed material slurry to obtain potassium-containing brine; solarizing the potassium-containing brine to obtain sylvite; carrying out hot dissolving onthe sylvite to obtain a dissolved solution; after concentrating the dissolved solution, obtaining supernatant and bottom flow containing sodium chloride particles; adding a filter aid into the supernatant and removing impurities to obtain a refined potassium chloride solution; cooling and crystallizing the refined potassium chloride, and carrying out solid-liquid separation to obtain the food-grade potassium chloride. The method provided by the invention has the advantages of resource saving, production cost reduction, convenience for operation and the like, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of inorganic salt industrial food processing, and more specifically relates to a method for preparing food-grade potassium chloride from potassium-containing tail salt. Background technique [0002] Food-grade potassium chloride is widely used in agricultural products, aquatic products, livestock products, fermented products, condiments, flavoring agents for convenience foods, etc., and has great market development potential. At present, the production of food-grade potassium chloride has not yet formed a scale in the western region, and there is a large market space. The diversified and high-value development of potassium salt products can promote the sustainable, healthy and sound development of the salt lake potassium industry, extend the industrial chain of the salt lake potassium industry, and make salt lake resources not only develop in the fields of industry and agriculture, but also contribute to food by incre...
