    Mar 20, 2017 · Abstract. Copper and cobalt usually coexist in the leachate of waste lithium ion batteries, sea nodules and other copper ore or by-product. Conventional methods for the separation of copper and cobalt hardly avoid some defects, such as longer extraction time, co-extraction and too many stages.

  • Liquid–liquid extraction - Wikipedia

    Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
