粉煤灰的高值化应用

ANALYSIS ON HIGH-VALUE APPLICATION OF FLY ASH

目前我国对粉煤灰的利用率较低,且多用于填埋及建筑材料。对粉煤灰中金属的提取及高效利用尤为重要。酒钢粉煤灰提铁项目针对粉煤灰的高效利用进行了深入研究,主要使用干式磁选机和风磁平板联合干选机组提取粉煤灰磁珠,然后运用于高炉炼铁、废水处理以及民用建筑等。

At present,the utilization rate of fly ash in China is relatively low,and it is mostly used for landfill and construction materials.The extraction and efficient utilization of metals in fly ash are particularly important.The fly ash iron extraction project of Jiugang has conducted in-depth research on the efficient utilization of fly ash,mainly using dry magnetic separators and wind magnetic flat plate combined dry separation units to extract fly ash magnetic beads,which are then used in blast furnace iron-making,wastewater treatment,and civil construction.
