  • Flotation Cell Control International Mining

    Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) air addition rate Many other parameters may vary such as feed rate, particle size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itselfThis manuscript develops a robust output regulator for the column froth flotation process in the presence of unknown disturbance In particular, motivated by relevant physical modeling setting, all information (including magnitude, phase, bias, and frequency) of the disturbance is unavailableRobust tracking control of column froth flotation process
