iron ore gravity

University of Minnesota's Mineral Pages Calcite

Once iron mining began though, the mineral's magnetic character provided an unexpected risk for the mining industry. Ore ships on the Great Lakes could not rely on compasses to plot their position or course because of the magnetite they carried. Before the advent of global positioning satellites transporting iron ore was a riskier endeavor.

Specific Gravity Of Metals Table CSGNetwork

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m). As specific gravity is just a comparison, it can be applied across any units.
