我国又一重大突破！

Core Viewpoint - The research team at the Qinghai Salt Lake Research Institute has achieved a significant breakthrough in the extraction and separation of lithium resources from salt lake brine, overcoming key technical challenges in the efficient separation of lithium, sodium, and potassium ions [1][3]. Group 1: Technological Breakthrough - The Qinghai Salt Lake Research Institute has developed a green and efficient lithium extraction technology, creating a new type of lithium-selective extractant that addresses environmental, safety, and cost control issues in traditional extraction systems [3]. - The new technology can increase the overall lithium ion recovery rate in lithium carbonate production by 15% to 20% and reduce costs by 30% [3]. Group 2: Industrial Impact - A demonstration line for the extraction of lithium from salt lake brine has been established in Qinghai Province, capable of producing battery-grade lithium carbonate at a scale of 10,000 tons, generating an additional output value of over 600 million yuan [3]. - The technology's water and energy consumption is more than 30% lower than industry standards, which is strategically significant for supporting the construction of a world-class salt lake industry base [3].
