what is specific gravity of 4.5 of iron ore fines? The specific gravity of iron ore fines at 4.5 indicates that it is denser than water, which has a specific gravity of 1. This means that iron ore fines would sink in water. Specific gravity is a measure of density relative to the density of water, so a higher value indicates a denser material.
