Difference Between Density and Specific Gravity


Both density and specific gravity describe mass and may be used to compare different substances. They are not, however, identical measures. Specific gravity is an expression of density in relation to the density of a standard or reference (usually water).

How to Find and Determine the Specific Gravity of a Rock


How to Obtain the Specific Gravity of Dry Solids. To obtain the per cent solids in a pulp, from the specific gravity of that pulp, the specific gravity of the dry solids in the pulp must be known. The following is a simplified procedure for obtaining this figure. Place a weighed amount, say 200 grams, of dry solids in a dry graduate.

Gravity separation - Wikipedia


Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Gravity flow of bulk solids | SpringerLink


Observation of a bulk material discharging from a hopper or flowing under gravity along a steeply inclined channel will immediately suggest similarities to the behaviour of liquids. Whilst there are certainly some similarities between the flow characteristics of bulk solids and liquids, the analogy is one that it is unwise to pursue.
