Study on Dewatering of Fine Coal by Combination of ...

Thus our aim was the evaluation of the impact of electrodes on the electrolysis-pressure-filtration effect on fine coal dewatering. The results of this study indicate that when the coal slurry concentration is 400g/L, and when the electrode is aluminum-aluminum (90V, 14min), we can achieve the best effect and the lowest moisture content of the filter cake, which is 10%. The electrolysis ...
