50 行 Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Physicists use 39.2F (4C) as the standard, but engineers ordinarily use 60F. In the International System of Units (SI Units), the density of water is 1.00 g/cm3 at the standard temperature.

Gravity concentration, a technology with its roots in antiquity, is based on the differential movement of mineral particles in water due to their different density and hydraulic properties. The method has seen development of a range of gravity concentrating devices, and the potential to treat dry to reduce reliance on often scarce water resources ( Chapter 10 ).

2020-10-31 Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed. The size that can be processed ranges from very coarse materials, coarser than 100 mm, concentrated through heavy media vessels or ROM jigs, to very fine particles, about 10 microns, concentrated through centrifugal processes.

Jigs • Jigging is one of the oldest methods of gravity concentration, normally used to concentrate relatively coarse material. • If the feed is fairly closed sized (e.g. 3-10mm), it is possible to achieve good separation of minerals with a small difference in their specific gravities (e.g. fluorite, sp. gr. 3.2, from quartz, sp. gr. 2.7).

"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.
