| Abstract: | The flotation dynamics characteristics and variation law of fine coals with different densities were studied. The relation between flotation rate and dosage of flotation reagent was also discussed. And the mathematics model on the relation between the flotation rate constant k for fine coal and different operation variables was established. In addition, the practical industry flotation was predicted based on the flotation rate constant k of slurry with different density and the continuous dynamics model of coal flotation. The result shows that corrected continuous dynamics model of coal flotation is reliable, and the prediction accuracy is good. |
