A new method for extracting lithium in a greener and more efficient way has passed Chinas state-level appraisal, paving way for its commercialization to boost the new energy sector. Lithium batteries are essential to power modern electronic devices, such as mobile phones, laptops and electronic cars.
Lithium is also used in medicine, pottery, glass and other industries. Lithium cells rely on lithium carbonate as the raw material. China imports 80 percent of its lithium carbonate, though it is rich in lithium resources, due to backward mining technology.
With traditional methods, 30-40 tonnes of waste are produced in making 1 tonne of lithium carbonate. It is also very costly to treat the waste. 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 worlds largest lithium mica mine. The provinces reserve of lithium oxide accounts for one-third of Chinas total.
