FIELD: metallurgy. SUBSTANCE: method of lithium extraction from solid waste involves preliminary calcination, preferably at 300-400 C, and leaching with hydrochloric acid up to complete conversion to chlorides and leaching with water after calcination. Method is used for processing solid waste containing aluminium-lithium alloys, slimes, slags, etc. EFFECT: enhanced degree of lithium extraction. 2 cl, 1 tbl
