Abstract
A combustion ash handling method of handling combustion ash discharged from a combustion furnace that combusts a petroleum-based fuel includes: separating the combustion ash into a heavy component and a light component by a dry-type separation technique; feeding the light component to the combustion furnace as a fuel; and recovering the heavy component. A metal such as vanadium is separated and extracted from the heavy component of the combustion ash.
