Boiler ash, produced by burning heavy fuel oil (HFO) in electrical power plants, is one of the most serious environmental problems facing oil-rich countries. However, boiler ash also contains some important industrial elements like V, Ni, Zn, etc., and has great potential for positive utilization. T...
