Qinghai Foshan Lithium Energy Development Co., Ltd., which holds a 38% stake in Foshan Lighting, and Qinghai Salt Lake Technology Development Co., Ltd. and Qinghai Weili New Energy Materials Co., Ltd. jointly established Qinghai Salt Lake Lanke Lithium Industry Co., Ltd. in July 2010 (below Referred to as “Lanke Lithium Industryâ€, the technical demonstration of the “Extraction of Lithium Carbonate from Brine by Adsorption Method†industrial demonstration device officially started the adsorption operation at 14:00 on September 3, 2010, until 2010. At 14 o'clock on the afternoon of the 10th, it continued for 168 hours.
After the successful completion of the 168-hour industrial demonstration, Lanke Lithium Company carried out technical transformation of the original production equipment. After the successful completion of the lithium extraction test of the 50M3 adsorption tower in April 2011, the annual output of 10,000 tons of high-purity high-quality lithium carbonate project In the process of technological transformation, industrial trial production was carried out. On June 6, 2012, the daily production capacity of lithium carbonate in the main workshop of the project exceeded 5 tons, and the grade reached 99.5%, and maintained continuous and stable production. With the accumulation of previous work results, The daily production capacity of lithium carbonate of Lanke Lithium Company will increase steadily on this basis.
The project achieved a breakthrough in the industrialization of high-purity and high-quality lithium carbonate extraction from high-magnesium-lithium-salt brine water resources by adsorption method; the project adopts energy-saving measures such as Yantian natural evaporation concentration and heat pump heating system; no chemical substances are added during magnesium-lithium separation process. To achieve cleaner production and recycling of waste. It is a demonstration project for energy saving and recycling economy; the project is the first application of the reverse osmosis device in the lithium extraction process, which greatly reduces the production cost and also saves a lot of fresh water; the project effectively improves the tail brine of the Chaerhan Salt Lake Utilization rate. The tail halogen utilization rate is from 15% to 15%. It provides reliable raw material guarantee for the development of lithium resources in China and the development of downstream products in the lithium carbonate industry.
