Latest Patents
Wenjing Wan holds a patent for a "Method for green and low-cost extraction of nickel-cobalt from laterite nickel ore." This method involves several key steps: first, an iron removing pretreatment is conducted by adding an iron removing agent to a high-pressure leaching solution of the laterite nickel ore. This process reduces the iron concentration to less than 0.2 g/L, resulting in a leaching solution. Next, nickel is adsorbed and enriched using a first resin adsorption process, yielding a nickel adsorption resin and a nickel adsorption tail liquid. The nickel adsorption resin is then desorbed to obtain a crude nickel solution. Following this, cobalt is extracted from the nickel adsorption tail liquid through a second resin adsorption process, leading to the production of a cobalt solution. Finally, a third resin adsorption process is applied to the crude nickel solution to remove copper, resulting in a purified nickel solution. This innovative approach not only enhances the efficiency of metal extraction but also minimizes environmental impact.
