摘要:
针对煤炭洗选过程中排放的大量煤矸石和浮选尾煤灰分偏低的现象,分析了尾矿再选的必要性,介绍了乌海地区利用液固流化床进行尾矿再选的典型工艺流程,通过对该工艺在赵守聪选煤厂的分选效果研究,发现液固流化床分选可以显著提高煤矸石发热量,并能够从浮选尾煤中提取合格精煤,具有显著的经济效益和环境效益,对尾矿再选研究提供了借鉴和参考。
关键词: 尾矿再选, 液固流化床, 破碎, 可能偏差E
Abstract:
With the present phenomenon of low ash content of great amount of coal gangue and flotation tailings discharged in the process of coal washing , the necessity of tailings recleaning was analized and typical process of tailings recleaning with liquid-solid fluidized bed in WuHai area was introduced .The separation effect of the craft in Zhao Shou Cong coal preparation plant was discussed and the results show that liquid-solid fluidized bed separation could improve the calorific value of coal gangue signally and get qualified clean coal from flotation tailings , which not only has remarkable economic benefit and environmental benefit but provides a reference for tailings recleaning research .
Key words: tailings recleaning, liquid-solid fluidized bed, crush, probable deviation E
