  • Method for enhancing leaching of metals in zinc hypoxide powder by mechanochemistry coupling with sonochemistry
    Patent number: 11453930
    Abstract: Disclosed is a method for enhancing leaching of metals in zinc hypoxide powder by mechanochemistry coupling with sonochemistry, comprising the following: mechanical activation: a raw material containing zinc hypoxide powder is mechanically activated so that an activated material is obtained; and ultrasonic treatment: the activated material is mixed with an acidic leaching solution to obtain a mixture, the mixture is subjected to ultrasonic treatment, and a liquid phase is obtained as the leachate. Mechanochemical activation and ultrasonic chemistry synergistically enhance the leaching efficiency and leaching rate of multiple metals through the destruction and cavitation of the zinc oxide powder structure. This process can indirectly reduce the concentration of the used acidic leaching solution and shorten the leaching duration.
