Abstract
The present writer has developed the measuring method on wettability between formed coal powder and water (See Journal of the Mining and Metallurgical Institute of Japan, Vol. 96, No. 11 10, P. 547).
In this report, he has made clear the relation between the wettability by above- mentioned method and the recovery of coal pellets in weight by O. A. method (See Fig. 5 and Fig. 6).
The apparatus of the above-mentioned O. A. method is shown in Fig. 3 and Fig. 4.
