乳化捕收剂对潞安煤的浮选试验研究
首发时间:2009-06-30
摘要:采用一种新型乳化药剂ZFC和柴油为捕收剂分别对潞安煤样进行了一系列浮选试验。试验表明,药剂性能优良,稳定性好,选择性高,促进了浮选性能,在基本保持精煤灰分不变的情况下,与柴油相比,使用ZFC作为捕收剂时,可提高精煤产率0.24-20.07%左右,可燃体回收率可提高0.33-21.33%。药剂用量少,节油率高达70%。通过润湿热的测定和浮选动力学的研究对ZFC的浮选机理进行了初步探讨。

Research on Flotation of Emulsified Collector for LA Coal
Abstract:Flotation experiments for Lu-an(LA) coal were conducted with two collectors that were diesel oil(DO) and a new type of emulsified reagent ZFC. Experimental results show that the reagent had excellent performance, well stability and high selectivity, which promotes the coal flotation. Compared with the flotation with diesel at the similar clean ash, the ZFC can increase clean coal recovery and combustible material recovery 0.24-20.07% and 0.33-21.33%, respectively. The dosage of ZFC is less than the used diesel oil and the rate of oil saving reaches up 70%. The flotation mechanism of ZFC was also studied by measuring wetting heat and researching Flotation Kinetics of LA coal.
