中文摘要: 以含锂废渣为原料,用水浸出,再用二氧化碳碳化的方法使氢氧化锂转化为碳酸锂和碳酸氢锂,实现了硼、锂的一步分离,并采用恒温热分解法处理碳酸氢锂溶液,制得碳酸锂。采用正交试验探究了达到最高回收率及产品纯度的条件。结果表明,此生产工艺简单,碳酸锂回收率可达94%以上,产品纯度可达90%以上。
Abstract:Lithium hydroxide is prepared from lithium-bearing waste by water leaching, and then transformed to lithium carbonate and lithium bicarbonate with carbon dioxide. One-step separation of boron and lithium is achieved. Lithium carbonate is produced from lithium bicarbonate solution by thermostatic decomposition. Orthogonal test is conducted to explore conditions to reach the highest yield and product purity. The results show that yield rate of lithium carbonate is 94% with purity of 90% above.
