In applications with higher specific gravity, more torque would be required to produce the desired result.

  3. From an internet site on definition of specific gravity: Specific gravity is the density of a substance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density (but without any units).

  11. Many attempts have been made to extend the application of the immersion method by causing a small fragment of a heavy min-eral to adhere to objects having a low specific gravity. In deter-mining the specific gravity of such a system by the ordinarv method, the specific gravity of a mineral is comparatively easy to obtain.

  14. As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity. A volumetric flask of one liter capacity provides the necessary accuracy.

  15. Specific gravity, also called relative density, is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance.

  16. Barite is chemically inert and insoluble. Each grade is used for certain specific applications. Barite is classified based on its purity, i.e. the concentration of barium sulfate present in barite. Accordingly, the specific gravity of barite varies. Barite with specific gravity of 3.9 g/cm3 or less falls under the up to Sp. Gr. 3.9 grade segment.

  17. The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:

  19. calculated mathematically by comparing the bulk specific gravity of a mixture with the maximum theoretical specific gravity of the mixture at the same asphalt content. The test method developed by Rice (ASTM D-2041) is the most accepted means of deter­ mining maximum theoretical specific gravity. Nevertheless, agen­

  20. 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).

  21. Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.
