Latest Patents

Peng Li holds a patent for a method titled "Method for extracting and recovering gold from aqueous solution." This patent outlines a comprehensive approach that includes several key steps. The first step involves gold extraction through electrocoagulation, where an electrolytic cell is used to produce iron hydroxide in-situ. This process captures gold from the aqueous solution and reduces it into gold nanoparticles. The second step focuses on the pickling and liquefaction of the precipitated iron sludge. Here, the obtained precipitate is dissolved in nitric acid to dissolve iron flocs after washing treatment. The final step involves the separation and recovery of gold using a nanofiltration membrane system. This system allows for the separation of nano-sized elemental gold from the solution, which is then washed with water to obtain pure elemental gold.
