Mineral and rock densities are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
Hence, density is a significant parameter and its determination requires similar care as the measurement of grade. This paper provides an overview of methods used to determine density within the Anglo American Group.

The incorporation of bulk density uncertainty for Mineral Resource and Mineral Reserves (MRMR) steps is of great importance for successful mine planning process. In practice, most mining projects use an average density value for each lithological type of the deposit.
A characteristic minimum registration time to detect a certain density anomaly varies from a few hours to about 10 days, depending on the geologic situation and the depth and design of the detector. The device is found to be most applicable for massive sulfide and iron exploration.This technique provides some new possibilities.

Traditional interpolation techniques in geostatistics were used to represent density spatial distribution in a block model, similarly to those used for grade estimation. This approach was developed and applied at a Brazilian iron ore mine. The results indicate MRMR are underestimated if density uncertainty is not considered.

Twenty different iron ore pellets, consisting primarily of Hematite (Fe2O3) phase, were subjected to 'simulated' reduction studies. A wide range of reduction time periods, Rt of 122 to 211 minutes, were obtained. Detailed microstructural characterizations were then conducted at different locations of ten selected specimens. The Rt did not …

The in situ bulk density includes the water naturally contained in the rock. This measure is important for estimation of the tonnage of material to be moved during mining. For resource estimates, however, we require the dry bulk density, which is the dry mass of the material divided by the in situ volume. Dry bulk density is used
