摘要
PROBLEM TO BE SOLVED: To provide a floatation method or the like of pulverized coal capable of imparting floating a property even to pulverized coal whose bonding force to oil drops is weak, that is [H/C×100] value is ≤80, to be impossible to apply the floatation method heretofore thereby applying the floatation method, and reducing the quality of oil to be used in a pulverized coal precipitation.;SOLUTION: The floatation method of coal for recovering the pulverized coal (c) from coal slurry S2 containing fine powdery coal having [H/C×100] value of 0-80 and ≤0.5 mm particle diameter is constituted so as to include a oil addition process for adding floatation oil A to the coal slurry S2, a shearing process for rapidly stirring the coal slurry S2 to impart a shearing force to the pulverized coal and the oil drops (a) of the floatation oil A and a floatation process for floating the pulverized coal (c) after the shearing process to clean and recover.;COPYRIGHT: (C)2004,JPO
