Specific Gravity: Mineral Properties The Mineral and

Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water. Minerals with a specific gravity under 2 are considered light, between 2 and 4.5 average, and greater than 4.5 heavy. Most minerals with a metallic luster are heavy.

Conversion Factors and the Specific Gravity of Minerals

Aug 18, 2020· 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.

7 Physical Properties of Minerals Used To Identify Them

Nov 10, 2019· Specific Gravity of Minerals . Specific gravity is the density of a material, in this case a mineral, compared to an equivalent volume of water. If a piece of galena has a specific gravity of 7.58, that means that it is 7.58 times heavier than a volume of

Specific gravity University of Auckland

Specific gravity Definition. A mineral's specific gravity is the ratio of its mass to the mass of an equal volume of water. For example, magnetite has a specific gravity value of 5.2, meaning 1cm 3 of magnetite will be 5.2 times as heavy as 1cm 3 of water. Test. Although this property can be precisely measured, it is often tested by simply hefting the specimen in the hand.

Donald B Peck Determining the Specific Gravity of a Mineral

The Specific Gravity for minerals is customarily rounded to two decimal places. The best estimate of the true Specific Gravity of your unknown mineral is the average Sp.G. of your samples. So sum the Sp. G. of the individual samples in Row 4 and divide by the number of samples, 5.
