The fundamental chemistry for selective adsorption of magnetizing reagent on coal-associated minerals to enhance the magnetic susceptibility of minerals have been established in Phase I study. The application of the results on coal cleaning is in progress in the Phase II study. The task in Phase II study for coal selection, preparation, and characterization is completed in this reporting period. The optimization of adsorption conditions for {minus}48 mesh ROM coals and flotation concentrates is about completed. Experiments have shown that successful coal cleaning can be obtained with this magnetizing reagent approach. The task to adapt the approach to various processing schemes is just initiated.
