Умови реалізації "мокрої" і "сухої" флотації вугілля і мінералів [PDF]
, 2014 Проведено аналіз умов реалізації "мокрої" і "сухої" флотації вугілля і мінералів. Показано, що "мокра" флотація переважає у більшості випадків. "Суха" флотація має підвищену імовірність, зокрема, для коксівного вугілля, флотоагрегати якого, у випадку її ...

Coal surface control for advanced fine coal flotation [PDF]
, 1990 The primary objective of this research project is to develop advanced flotation methods for coal cleaning in order to achieve near total pyritic-sulfur removal at 90% Btu recovery, using coal samples procured from six major US coal seams. Concomitantly, the ash content of these coals is to be reduced to 6% or less. Work this quarter concentrated on the
