METHOD OF PREPARING LITHIUM-CONTAINING FLUORINE SALTS FOR ELECTROLYTIC ALUMINIUM PRODUCTION |
摘要 |
FIELD: aluminium production by electrolysis of melted salts. SUBSTANCE: in order to prepare lithium-containing fluorine salts for electrolytic aluminium production, lithium-containing component is mixed with sodium-containing component and the resulting product is heat treated. Sodium-containing component is clarified solution resulting from gas purification in electrolytic aluminium production, lithium to fluorine weight ratio being maintained at 0.04-0.37. EFFECT: reduced cost price of the product. 5 cl, 1 tbl
