Title: Cuong V Luong: Innovator in Hydrometallurgical Processes
Introduction
Cuong V Luong is a notable inventor based in Mississauga, Canada. He has made significant contributions to the field of hydrometallurgy, particularly in the extraction and separation of valuable metals such as nickel and cobalt. With a total of 3 patents to his name, Luong's work is recognized for its innovative approaches to metal recovery.
Latest Patents
One of Luong'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. An aqueous feed solution originating from acid leaching is utilized, containing nickel and/or cobalt ions. The pH of the solution is maintained between about 2 and 6. The aqueous feed solution is then contacted with a water-immiscible organic phase containing an extractant to load the nickel and/or cobalt metal ions, forming 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 sufficiently low levels of chromium (VI) ions, iron (III) ions, and copper ions to allow for the repeated use of the extractant. After separation from the aqueous feed solution, the metal-bearing organic phase is contacted with an aqueous strip solution to recover the loaded nickel and/or cobalt.
