In this case, the high-density iron ore particles sank to the bed bottom as the iron concentrate, thereby improving the concentrate grade. However, when the gas velocity exceeded the limit, the bed became unstable because of the bubbling turbulence, which affected the density-based separation of coarse iron ore particles.
SG might also be used (as Archimedes did) to distinguish pure gold (SG = 19.3) from 14K gold (SG =13.3) or pyrite (SG = 5.1). Some specific gravities of minerals are shown below. Online mineral vendors sell equipment for determining specific gravity, but it is simple to do in the lab. Specific gravity is related to density, but it is unitless.

Bulk Density – Measurement Key points. Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil ...

Adjustment factors, where required, are used to convert determined density to bulk density. Bulk density implies dry bulk density; however, it always best to confirm this and precede the term with 'dry' or 'wet'. Only dry bulk density should be used in resource estimation because all assays are done on a dry basis. The same dry basis ...
particles; this is known as the 'tapped bulk density.' Bulk density of free-flowing powders or granular materials can be determined by filling a container of known volume, after which the material is weighed and the 'loose bulk density' can be estimated (Fig. 13). The container is then tapped and refilled until the

procedure for bulk density determination was based on the work of Lipton (2001) 'Water Dis-placement Method 4'. In this method, the bulk density is calculated from the relationship between the sample weight and the water displa-cement caused by the sample immersion in a graduated container. (2) In the second step, bulk density was estimated

One specific note to remember is that bulk density is used for apron feeders and not solid density like for other mineral processing equipment. So why is bulk density so important?
