    Deep learning-based ash content prediction of coal

    For coal flotation, simple CNN can classify the various flotation conditions (air flow rate, frother dosage, slurry solids, froth depth, and collector dosage), and the classification accuracy is higher than that of the artificial neural network , . Their success on CNN, as a flotation condition that can change the ash content, proves the

    Gas Dispersion Measurements in Coal Flotation Cells

    Coal flotation across the world has undergone major changes over the past thirty years. In a number of new coal flotation plants, the traditional mechanical flota-tion cells have been replaced by pneumatic flotation cells, such as the Jameson Cell and Microcel column cells. Significant steps have also been taken in the under-standing of what happens beneath the froth
