    Second, the relative effects of porosity, mineralogy of gangue minerals, and mineralogy of iron minerals have also not been examined. An understanding of specific gravity is useful for purposes other than the estimation of the iron content of rocks. The bulk specific gravity of ores is needed in order to calculate ore reserves.
