What is Lithium Extraction and How Does It Work?
What is Lithium Extraction and How Does It Work?

The crushed mineral powder is combined with chemical reactants, such as sulfuric acid, then the slurry is heated, filtered, and concentrated through an evaporation process to form saleable lithium carbonate, while the resulting wastewater is treated for reuse or disposal. Other lithium extraction processes
