METHOD OF PROCESSING MINERALS Russian patent published in 2015 - IPC C22B3/14 C22B34/14 C22B34/12 C22B34/24

Abstract RU 2553150 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of processing material which contains a mineral and/or a metal oxide/silicate obtained from a mineral or associated with a mineral. The method includes processing raw material by reacting a mineral and/or metal oxide/silicate obtained from the mineral or associated with the mineral with ammonium bifluoride of general formula NH₄F·xHF, wherein 1<x≤5. The reaction product is an ammonium fluorometal compound, which is subjected to thermal treatment for thermal decomposition thereof to obtain an anhydrous fluoride.

EFFECT: rapid, cheap anhydrous process of producing anhydrous fluorides from natural minerals.
