The initial evaluation used a tonnage factor of 12–13 ft3 to the ton (equivalent to a bulk specific gravity of 2.5–2.7), which would correspond to a typical figure for solid rock. Three separate mining groups had reported this value, and it was not questioned (G. Cole, 1993, pers. commun.).

Specific Gravity Range: Spiral concentrators work best when there is a significant difference in specific gravity between the valuable minerals and gangue material. Spiral concentrators are widely used in mineral processing operations, especially for the concentration of heavy minerals like zircon, rutile, iron ore, and coal.

Particle density is similar to the specific gravity of a solid and is not impacted by land use. Particle density is approximated as 2.65 g/cm3, although this number may vary considerably if the soil sample has a high concentration of organic matter, which would lower particle density, or high-density minerals such as magnetite, garnet ...

It has a specific gravity ranging from 4.9 to 5.3. Limonite (FeO(OH)·nH2O): Limonite is a yellowish-brown iron ore mineral that forms as a result of weathering and hydration of other iron-bearing minerals, such as hematite and magnetite. Limonite is typically amorphous or earthy in texture, and it often contains goethite (FeO(OH)) as an ...

Where dH = specific gravity of the heavy mineral dF = specific gravity of the fluid dL = specific gravity of the light mineral Generally, when the quotient is greater than 2.5 (whether positive or negative), then gravity separation is relatively easy. With a decrease in the value of the quotient the efficiency of the

Bulk density of these ores varies between 2.1 and 2.9 and the specific gravity ranges from 3.4 to 4.7. Lateritised hard ores are also found along with this ore type. Hard massive ores typically consist of 64–68% iron, 1.5–2.5% silica, 1.0–3.0% alumina and 0.030–0.060% phosphorus ( Table 2 ).

The photo in Figure 3.75 shows a gold nugget with quartz beneath it. It came from a placer. Gold has specific gravity of about 19.3 and quartz has specific gravity of 2.7. The specific gravity of a mineral depends, in part, on how its atoms are packed together within a crystal.
