Использование: для переработки твердых отходов, содержащих алюминий-литиевые сплавы, шламы размерного химического их травления, шлаки, образующиеся при производстве алюминий-литиевых сплавов. Цель изобретения: повышение степени извлечения лития. Сущность изобретения: способ извлечения лития из твердых отходов заключается в том, что перед прокаливанием, предпочтительно при 300 - 400oС, отходы предварительно выщелачивают слояной кислотой до полного перевода в хлориды, а после прокаливания - выщелачивают водой.Use: for processing solid waste containing aluminum-lithium alloys, sludges of size chemical etching, slags formed during the production of aluminum-lithium alloys. The purpose of the invention: increasing the degree of extraction of lithium. The inventive method of extracting lithium from solid waste is that before calcination, preferably at 300 - 400 o C, the waste is pre-leached with ply acid to complete conversion to chlorides, and after calcination - is leached with water.
