入料组成对细粒煤泥浮选的影响

Influence of Flotation Feed Composition on Fine Coal Flotation

为了研究+0.074 mm粒级煤泥粒度与含量对-0.074 mm粒级煤泥浮选的影响规律,提高-0.074 mm粒级煤泥的分选精度。分别将0.5~0.25、0.25~0.125、0.125~0.074 mm 3种粒级煤泥按不同比例添加入-0.074 mm粒级煤泥中,并进行了浮选试验、泡沫稳定性试验、精煤水回收率试验,研究了浮选入料组成对浮选泡沫稳定性、精煤水回收率及-0.074 mm粒级煤泥浮选指标的影响规律。

In order to study the + 0.074 mm level coal particle size and content on the-0.074 mm graded the influence law of coal slime flotation, Increase to-0.074 mm graded slime separation precision. Will be 0.5 ~0.25、0.25 ~0.125、0.125 ~0.074 mm three grade coal slime graded according to the different proportion of added to-0.074 mm in the coal slurry, and the flotation test, the foam stability test, water recovery rate test, studied the flotation into the material composition on the flotation foam stability, water recovery and-0.074 mm graded the influence law of coal slime flotation indexes.
