METHOD FOR PRODUCING ALUMINUM FLUORIDE Russian patent published in 2022 - IPC C01F7/50

Abstract RU 2772533 C1

FIELD: chemical technology.

SUBSTANCE: invention relates to chemical technology and ecology and can be used in the industrial production of the base product for the electrolytic production of aluminum. A mixture containing ammonium fluoride (NH₄F) as a fluorine-containing reagent and aluminum hydroxide (Al(OH)₃) as an aluminum-containing reagent is prepared, and it is supplied in sprayed form to a zone with a temperature of 350-550°С. To obtain ammonium fluoride, waste fluorosilicic acid from the industrial production of phosphoric acid from apatite concentrate is treated with an ammonia solution and the resulting silicon dioxide (SiO₂) is separated.

EFFECT: process of obtaining aluminum fluoride (AlF₃) is ensured, its yield is increased, the environment is improved due to the use of waste products from the industrial production of phosphoric acid.
