Latest Patents
One of Laundry's latest patents is a process for the extraction and separation of nickel and/or cobalt. This invention provides a hydrometallurgical process for the recovery of metals, utilizing an aqueous feed solution derived from acid leaching. The solution contains nickel and/or cobalt ions, and the pH is maintained between about 2 and 6. The process involves contacting the aqueous feed solution with a water-immiscible organic phase containing an extractant, which loads the metal ions to form a metal-bearing organic phase. The extractant includes at least one organic soluble dithiophosphinic acid, alkali, alkaline earth metal, or ammonium salt thereof. The aqueous feed solution is designed to have low levels of chromium (VI) ions, iron (III) ions, and copper ions, allowing for the repeated use of the extractant. After separation from the aqueous feed solution, the metal-bearing organic phase is treated with an aqueous strip solution to recover the loaded nickel and/or cobalt.
