A clean coal ash secondary flotation system relates to the technical field of coal washing, and adopts the technical scheme that the clean coal ash secondary flotation system comprises a flotation machine, a first outlet of the flotation machine is connected with a flotation column through a dehydration system, a second outlet of the flotation machine is connected with the flotation column, and a third outlet of the flotation machine is connected with a mud barrel. The technical scheme has the beneficial effects that the flotation machine is matched with the flotation column, and the three characteristics that the flotation column is high in fine fraction separation precision, horizontal separation is good in coal slime dehydration effect and free of caking, and the hydraulic cyclone is high in classification precision are utilized, so that flotation is completely dried and squeezed on the premise that dense medium clean coal is not subjected to ash back, and the yield of the clean coal is maximized. 一种精煤灰分二次
