山西煤样的浮选实验研究
首发时间:2011-07-11
摘要:泡沫浮选是当今处理细粒煤泥的重要手段之一。浮选技术最重要的是如何选择性提高精煤回收率,而众多的浮选工艺中,改进浮选药剂又是提高浮选效率最有效的方法,其中对浮选药剂进行乳化是改进浮选药剂的一种重要的方法。本文使用乳化柴油、AEP-2、柴油、煤油、乳化煤油五种捕收剂,分别对山西六种煤样进行浮选实验,比较不同药剂的浮选,特别比较了煤油和柴油乳化前后对不同煤样的浮选效果。

Research of Shanxi Coal Floatation
Abstract:Froth flotation is one of the most methods of dealing with slime coal at present. How to selectively enhance the clean coal recovery selectively is the most important fact in Flotation Technology.And in all those flotation processes , the most effective way of improving flotation efficiency is ameliorating the flotation regent,which emulsifying the flotation regent is a important way of ameliorating it.As a result, five collectors such as emulsified diesel oil, AEP-2, diesel oil, kerosene, and emulsified kerosene were used to do floatation with six Shanxi coal samples, and at the same time, compare effects of different flotation agents and also compare effects of diesel and kerosene oil befor or after emulsification especially.
Keywords: slime coal floatation collector
