CORRECTION LITHIUM-CONTAINING ADDITIVE TO ELECTROLYTE FOR PRODUCTION OF ALUMINUM Russian patent published in 2002 - IPC

Abstract RU 2180020 C2

FIELD: aluminum production. SUBSTANCE: proposed lithium-containing additive to electrolyte for production of aluminum is added with calcium chloride and magnesium fluoride with following proportion of components, per cent by mass: calcium chloride 15.0-40,0; magnesium fluoride 0.5- 40.0; lithium-containing component 30.0-70.0. In the capacity of lithium-containing component there can be used lithium carbonate, lithium aluminate, lithium-containing sodium cryolite and/or lithium cryolite. EFFECT: increased technical-and- economic indices of process of electrolysis, prolonged service life of electrolyzer, improved ecological situation and working conditions. 4 cl
