Title: Innovations of Chu Yong Cheng in Cobalt and Nickel Separation
Introduction
Chu Yong Cheng is an accomplished inventor based in South Lake, Australia. He has made significant contributions to the field of hydrometallurgy, particularly in the separation of cobalt and nickel from various solutions. With a total of 3 patents, his work has implications for both industrial processes and environmental sustainability.
Latest Patents
One of his notable patents is a solvent extraction process for separating cobalt from nickel in aqueous solutions. This innovative process involves subjecting the solution to extraction, utilizing the kinetic differences between nickel and cobalt to achieve a partial separation. By controlling the extraction duration, a major portion of cobalt and a minor portion of nickel can be extracted, resulting in a loaded extractant enriched in cobalt and a cobalt-depleted raffinate containing nickel. This method can be integrated into hydrometallurgical processes for extracting nickel and cobalt from ores or concentrates.
Another significant patent by Cheng focuses on the separation of nickel and cobalt from impurities in leach solutions. This process employs solvent extraction using carboxylic acids, hydroxyoximes, and kinetic accelerators to effectively separate nickel and cobalt from impurity elements such as calcium and magnesium. This innovation enhances the efficiency of metal recovery from leach solutions.
