About Bulk Density . Are bulk density and specific gravity the same? A bulk density and specific gravity are not the same. A bulk density is a ratio of mass to volume of soil. Specific gravity is a ratio of the density of a specific object to the density of a common substance, which usually is water. Why does bulk density increase with depth?

Iron ore. Iron is the fourth most abundant element in the Earth's crust, but economic concentrations are dominated by comparatively rare iron oxide forms; magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeOH), limonite (FeO(OH)nH 2 O) and siderite (FeCO 3).The mineralogy of iron ore impacts its commercial value and how it is processed.
