Latest Patents

Zhi He's latest patents include a method and system for preparing lithium carbonate from lithium ore. This invention outlines a process that begins with preparing lithium sulfate leachate from lithium ore concentrate. It involves removing iron and aluminum from the leachate by adding alkali, followed by the removal of calcium and magnesium through an ion exchange method. The process culminates in the addition of a saturated solution of soda ash to precipitate lithium carbonate, which is then filtered, washed, and dried to yield a high-purity final product. This method not only reduces production costs but also enhances the purity of lithium carbonate.

Another significant patent is a method for treating wastewater generated during the spherical nickel hydroxide production process. This invention employs a combined membrane treatment process to systematically address wastewater at all stages of production. By significantly reducing the concentration of crude wastewater, the method alleviates the treatment burden and energy consumption during evaporation, offering notable environmental benefits. The membrane treatment system is characterized by its ease of control and simple operation, ensuring that the quality of some produced water meets purified water standards.
