灵石煤泥可浮性分析及选别试验研究

对灵石煤泥的可浮性进行了评价,并对该煤泥可浮性差的潜在原因进行了分析。采用药剂乳化的方法,利用实验室旋流-静态微泡浮选柱作主体分选设备对其进行选别,结果表明,对该难浮煤泥进行乳化柴油浮选柱选别可以显著的降低捕收剂用量,提高精煤可燃体回收率。乳化柴油浮选柱选别是处理该难浮煤泥的有效途径,用药量少,浮选指标好,经济效益显著。

The floatability analysis and experimental study on flotation of Lingshi fine coal

This paper assessed the floatability of Lingshi coal slime and analysed the reason of its poor floatability. Using the technology of emulsifying diesel, this experiment took laboratory cyclonic Static microbubble flotation column as the chief separation equipment to deal with the coal slime. The experiment results shown that this technology could reduce the consumption of collector and improve the recovery rate of clean coal. As an efficient way of treating the hard-to-float coal slime, this technology consumes fewer reagents and could achieve good flotation results, which could improve economic benefit significantly.
