Density of Minerals
Definition
Density (or Specific Gravity) is a very important property of minerals. The calculation is fairly simple - weight/volume. It is measured using various apparatus and techniques which are covered in most mineralogy textbooks. These are:
1.Jolly Balance
2.Beam Balance
3.Pycnometer
4.Heavy Liquids
Of these methods, the jolly and beam balance methods are best suited for mineral specimen work. The apparatus to do these measurements are simple and can be inexpensively constructed (Sinkankas, 1966).
Density=(weight in air - weight in water)/weight in air.
The pycnometer and heavy liquids are best suited for the density measurement of fine or very small particles.
The mineralogy database has placed all the density information in the following tables:
Metallic Minerals by Density
Non-metallic minerals by density
Histogram of Mineral Density and Dana Classification
Here is the measured density data in the mineralogy database compared to the Dana Classification. As a rule, organics, carbonates, and sulfates are light; oxides, sulfides, and elements are heavy; silicates and phosphates are in between.

Density
Absolute: Mass per unit volume. Absolute density considers only the actual volume occupied by the material expressed in pounds per gallon (ppg) or pounds per cubic foot (lb/cu. ft. Bulk: Mass per unit volume. Bulk density is a mass per unit bulk volume which includes the actual volume of the material plus the volume of trapped air.

Density
The ratio of a body's mass to its volume.The density of water is 1000 kg/m3 ; the Sun is about 1400 kg/m3; a white dwarf (like Sirius B) 4 x 109 kg/m3; a neutron star around 1017 kg/m3. If the density of the universe is greater than 2 x 10 -26 kg/m3 (about 12 nucleons/m3) then the expansion will cease and a Big Crunch ensue.

density
In a facsimile system, a measure of the light transmission or reflection properties of an area of an object. (188 ) Note 1: Density is usually expressed as the logarithm to the base 10 of the ratio of incident to transmitted or reflected irradiance. Note 2: There are many types of density, such as diffuse, double diffuse, and specular density, each of which will usually have different numerical values for different materials. The relevant type of density depends on the type of optical system, the component materials of the object, and the surface characteristics of the object.

Density
Mass per unit volume, expressed in grams per cubic centimeter. Rock or formation densities are usually measured as either saturated bulk densities or grain densities. For gravity interpretation, the contrasts between rock bulk densities are of primary interest since these contrasts are responsible for the anomalous gravity field.

For gravity interpretation, the contrasts between rock bulk densities are of primary interest since these contrasts are responsible for the anomalous gravity field.
Rock bulk densities have been shown to vary as a function of geologic age, lithology and depth of burial. Rock densities typically range from 1.9 g/cm3 to 3.0 g/cm3.

Density
Density means pounds per cubic foot. The cubage of loose articles or pieces, or packaged articles of a rectangular, elliptical, or square shape on one plane, shall be determined by multiplying the greatest straight line dimensions of length, width, and depth in inches, including all projections, and dividing the total by 1728 (to obtain cubic feet). The density is the weight of the article divided by the cubic feet thus obtained.

Density
How tightly information is packed together on a storage medium (tape or disk). A higher density means that data are closer together, so the medium can hold more information. Floppy disks can be single-density, double-density, high-density, or extra-high-density. To use a double-density, high-density, or extra-high-density disk, you must have a disk drive that supports the density level. Density, therefore, can refer both to the media and the device.
The table shows the storage capacities of double- and high-density floppies on the PC and the Apple Macintosh.
