Description

Technical Field

[0001] The utility model relates to the technical field of mother liquor treatment, in particular to a mother liquor precipitation device. Background Art

[0002] Fluorine is ubiquitous in rare earth ores, but excessive levels can affect the quality of rare earth products, particularly during subsequent processing. By utilizing the unique reaction properties of rare earth elements (such as lanthanum, cerium, and yttrium) with fluoride ions, a soluble rare earth salt (such as lanthanum nitrate), a soluble calcium salt (such as calcium nitrate), and a phosphate (such as disodium hydrogen phosphate) are added. After adjusting the pH of the mother liquor, the rare earth ions, calcium ions, and phosphate ions react with the fluoride ions to form an insoluble lanthanum-doped fluorapatite precipitate, thereby removing fluorine. The various materials are mixed and stirred to react. After the reaction is complete, solid-liquid separation is performed to obtain a rare earth solution with a low fluoride content. A precipitation device is required to mix and stir the materials, facilitating the reaction.
