simultaneous recovery of vanadium and nickel from power,dec 01, 2014 1. introduction. fly ash is a solid residue which is collected in off-gas treatment system of power plants using heavy fuel oils. this residue is an important secondary resource for vanadium after primary resource of the ore concentrates and the metallurgical slag (xiao et al., 2010).the production of these fly ashes is of environmental concern (tsai and tsai, 1998, al-ghouti et al., 2011)..fly ash uses properties classification and advantages,may 23, 2020 fly ash uses, properties, classification and advantages. fly ash is a coal combustion product that is composed of the fine particles of burned fuel that are driven out of coal-fired boilers together with the flue gases. fly ash is a multifunctional material and can be used for different purposes, its utilization depends on local conditions.
