Latest Patents
Guofu Dai holds a patent for a method titled "Method for extracting and recovering gold from aqueous solution." This innovative process involves several key steps: first, gold is extracted from an aqueous solution through electrocoagulation, where an electrolytic cell produces iron hydroxide in-situ to capture gold and reduce it into nanoparticles. Next, the precipitated iron sludge undergoes pickling and liquefaction, where it is dissolved in nitric acid to remove iron flocs. Finally, gold is separated and recovered using a nanofiltration membrane system, which isolates nano-sized elemental gold from the solution, resulting in pure elemental gold.
