At present,the utilization rate of fly ash in China is relatively low,and it is mostly used for landfill and con-struction materials.The extraction and efficient utilization of metals in fly ash are particularly important.The fly ash iron ex-traction 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.
