New process recovers five times more lithium from waste than existing technology

“The key advantage is that it works in a wider pH range of 5 to 11 compared to other direct lithium extraction methods,” Parans Paranthaman, ORNL Corporate Fellow and co-author of the papers that present these findings, said in a media statement.  The patent-pending acid-free extraction process takes place at 140 degrees Celsius, compared to traditional methods that roast mined minerals at 250 degrees Celsius with acid or 800 to 1000 degrees Celsius without acid. The technique works based on lithiation, during which an aluminum hydroxide powder extracts lithium ions from a solvent to form a stable layered double hydroxide,

The Imperative to Preserve Earth’s Vital Ecosystems: A Call to Action for Investors and Governments

The latest study presents a chilling reality – to adhere to the Paris Agreement and sustain global temperatures within a 1.5°C threshold, the sanctity of critical ecological zones must be protected, devoid of any oil extraction. These vulnerable areas, encompassing natural reserves, biodiversity hotspots, Indigenous territories, and urban landscapes, are essential for maintaining a delicate ecological balance. Despite the significance of safeguarding these areas, abstaining from extracting oil and coal alone cannot ensure compliance with the Paris Agreement’s stipulations. A deeper, more profound shift is required to align with global climate objectives. A Fresh Navigation Map Within this landscape, the
