• Data-Driven Approximated Optimal Control of

    Sulfur flotation process is a typical industry process with complex dynamics. For a sulfur flotation cell, the structure of the system model could be derived using first-principles and reaction kinetics. However, the model parameters cannot be obtained under certain working conditions. In this paper, by using adaptive dynamic programming (ADP), we establish a data-driven optimal control

  • Chalcopyrite Flotation without Collector - Surface

    If the flotation is caused by elemental sulfur, one would expect to see a larger amount of elemental sulfur on the chalcopyrite sample conditioned at +215 mV. The reverse is found to be the case, however. The shoulder at approximately 164 eV, indicating the presence of elemental sulfur, is stronger at the potential of -236 mV than at +215 mV.
