  • Method and system for predicting content of multiple components in rare earth extraction process
    Patent number: 11593607
    Abstract: Described is a method for predicting multiple components' content in a case that rare earth ions with and without color feature coexist, and relates to component content prediction in rare earth extraction process. It is difficult to quickly/accurately detect component's content in rare earth extraction process. Because of relatively large difference between images' color features of CePr/Nd mixed solution with colorless Ce ions and Pr/Nd solution, detecting content method of single rare earth element based on color feature is no longer applicable.
    Type: Grant
    Filed: September 9, 2019
    Date of Patent: February 28, 2023
