Method for extracting lithium from electrolytic aluminum lithium-containing material and lithium-containing glass through compounding
The invention relates to an electrolytic aluminum lithium-containing material and lithium-containing glass composite lithium extraction method. The preparation method comprises the following steps of: mixing an electrolytic aluminum lithium-containing material and a lithium-containing glass block in proportion, crushing into particles, adding an auxiliary agent, and mixing and ball-milling until the fineness is greater than 150 meshes; the mixed material is fed into a ball press machine to be pressed into blocks, then the blocks are transferred into a roasting furnace to be subjected to ventilation calcination for 3-8 h at the temperature of 500-800 DEG C, calcination clinker is obtained through natural cooling and crushing, tail gas is absorbed through spraying, and absorption liquid is treated through lime. The clinker is stirred and leached with clear water, the leaching temperature is 50-90 DEG C, the ratio of water to materials is (1-3): 1, a lithium solution and filter residues are obtained after filtering separation, and the filter residues are sent to a cement plant to be used as cement. The lithium concentration of the filtrate is (8-10) g/L, sodium carbonate is adopted for lithium precipitation to obtain lithium carbonate, and the comprehensive yield of lithium is larger than 90%.
本发明涉及一种电解铝含锂物料与含锂玻璃复合提锂的方法。其制备过程是：先将电解铝含锂物料和含锂玻璃块按比例混合破碎成颗粒状，再添加助剂后进行混合球磨，细度＞150目；混合物料送入压球机中压制成块状，再转入到焙烧炉中500℃‑800℃通风煅烧3h‑8h，自然冷却破碎得到煅烧熟料，尾气采用喷淋吸收，吸收液采用石灰处理。将熟料采用清水搅拌浸出，浸出温度50℃‑90℃，水和物料比例为(1‑3):1，过滤分离后得到锂溶液和滤渣，滤渣送到水泥厂做水泥用。滤液锂浓度为(8‑10)g/L，采用碳酸钠进行沉锂得到碳酸锂，锂综合收率＞90%。
