Claims (3)

1. Способ получения литийсодержащих фтористых солей для электролитического производства алюминия, включающий смешение литийсодержащего реагента в виде элюата селективной сорбции лития, выделенного из природного рассола на неорганическом сорбенте и представляющего собой водный раствор смеси хлоридов лития, кальция и магния, с фторсодержащим реагентом, отличающийся тем, что фторированию подвергают смесь карбонатов лития, кальция и магния, предварительно осажденных из элюата путем его обработки содой.1. A method of producing lithium-containing fluoride salts for the electrolytic production of aluminum, comprising mixing a lithium-containing reagent in the form of an eluate of selective sorption of lithium isolated from natural brine on an inorganic sorbent and representing an aqueous solution of a mixture of lithium, calcium and magnesium chlorides with a fluorine-containing reagent, characterized in that a mixture of lithium, calcium and magnesium carbonates, previously precipitated from the eluate by treatment with soda, is subjected to fluorination. 2. Способ по п.1, отличающийся тем, что смесь карбонатов лития, кальция и магния, получают непосредственно из природного рассола путем осаждения их содой, а дополнительное количество лития, необходимое для того, чтобы массовое содержание литиевого компонента (в пересчете на карбонат лития) в смеси карбонатов составляло 30-50%, вводят в смесь в виде карбоната, и/или гидроксида, и/или моногидрата гидроксида лития, а также их смесей в любых соотношениях.2. The method according to claim 1, characterized in that the mixture of lithium, calcium and magnesium carbonates is obtained directly from natural brine by precipitation with soda, and an additional amount of lithium is necessary so that the mass content of the lithium component (in terms of lithium carbonate ) in the mixture of carbonates was 30-50%, introduced into the mixture in the form of carbonate and / or hydroxide and / or lithium hydroxide monohydrate, as well as mixtures thereof in any ratio. 3. Способ по п.1, отличающийся тем, что в качестве фторсодержащего реагента используют фтористоводородную кислоту, газообразные фтор и/или фтористый водород или их смеси, а также отходящие фторсодержащие газы алюминиевого производства.3. The method according to claim 1, characterized in that hydrofluoric acid, gaseous fluorine and / or hydrogen fluoride, or mixtures thereof, as well as waste fluorine-containing aluminum gases are used as the fluorine-containing reagent.
