Latest Patents
One of Xiufen Li's latest patents is titled "Method for synchronously recovering metal and elemental sulfur." This invention discloses a method for recovering metal and elemental sulfur from sulfide ore tailings. The process involves transferring metal and sulfur elements from a solid phase to a liquid phase through leaching in an anode chamber. The metal ions are then recovered as hydroxide precipitate in a first cathode chamber, while sulfate ions are recovered as elemental sulfur precipitate in a second cathode chamber. This method achieves a metal recovery rate of up to 89.4% and an elemental sulfur recovery rate of up to 45.7%. The process is characterized by its simplicity, low operating costs, and high recovery rates, while also alleviating equipment corrosion and avoiding secondary pollution.
Another significant patent is the "Comprehensive evaluation method for performance of contaminated flat membranes." This invention relates to the field of sewage and waste resource technology. It involves analyzing the surface elements of contaminated membranes to determine the type of contamination. Different cleaning schemes are designed based on the contamination type to obtain a sample membrane. The method quantitatively defines the difference between old and waste membranes, providing a basis for the selection and regeneration of contaminated membranes.
