A new method for extracting lithium has passed China’s state-level appraisal

Qiu Zumin, professor of the institute of environmental science and engineering in Nanchang University, said the new lithium extraction technology has passed the national scientific and technological achievements appraisal. It is expected to replace current lithium extraction methods in China, which have been blamed for producing huge amounts of waste and also for having low profitability.

With the word’s growing reliance on lithium-ion batteries – from electronic devices, cars, medicine and other industries – lithium cells rely on lithium carbonate as the raw material. China imports approximately 80 percent of its lithium carbonate, though it is rich in lithium resources, due to outdated mining technology.

With traditional methods, 30-40 tonnes of waste are produced in generating 1 tonne of lithium carbonate. Treatment of this waste very expensive.

The new method is jointly developed by the Jiangxi Haohai Lithium Energy, Nanchang University and other institutions. It can separate all the elements in lithium micas.

Peng Guiyong, chair of Haohai, said the company plans to invest 1 billion yuan (156 million U.S. dollars) to build a production line with an annual capacity of 40,000 tonnes of lithium carbonate.

Jiangxi boasts the world’s largest lithium mica mine. The province’s reserve of lithium oxide accounts for one-third of China’s total.


中国找到更环保的方法制造锂电池

据中国媒体报道,一种更环保、更有效的提取锂的新方法已经通过了中国的国家级评估,为其商业化铺平了道路,以促进新能源领域的发展。

南昌大学环境科学与工程学院教授邱祖民教授表示,新的锂提取技术已通过国家科技成果鉴定。预计将取代中国目前的锂提取方法,目前的提取方法因产生大量的废物和盈利能力低而被指责。

随着世界越来越依赖锂离子电池—从电子设备、汽车、医药和其他行业—锂电池依靠碳酸锂作为原材料。中国尽管锂资源丰富,但是开采技术落后,大约进口80%的碳酸锂。

采用传统的方法,生产1吨碳酸锂,需产生30-40吨的废物。这种废物的处理非常昂贵。

新方法由江西昊海锂能、南昌大学等机构联合开发。它可以分离锂云母中的所有元素。

昊海董事长彭桂永表示,公司计划投资10亿元人民币(1.56亿美元)建设年产4万吨碳酸锂的生产线。

江西拥有世界上最大的锂云母矿。该省氧化锂储量占中国总量的三分之一。
