Latest Patents

Clark's latest patents include methods for the leaching of Ni-Cu-Fe-S matte and the separation of cobalt from nickel solutions. In his first patent, he describes a process where nickel is selectively leached efficiently and rapidly from Ni-Cu-Fe-S matte under oxidizing conditions at ordinary pressure. This process involves controlling the acid-to-copper mole ratio in the leaching solution, temperature, and sulfur content of the matte, resulting in an enriched nickel solution that is low in copper and iron. His second patent provides a method for separating cobalt from a nickel solution containing cobalt in the cobaltous state and an ammonium salt. This method involves ozonation while maintaining a specific pH, allowing for the oxidation of cobalt to the cobaltic state and its subsequent precipitation.
