Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Dairy product - Separation | Britannica

Separation. Most modern plants use a separator to control the fat content of various products. A separator is a high-speed centrifuge that acts on the principle that cream or butterfat is lighter than other components in milk. (The specific gravity of skim milk is 1.0358, specific gravity of heavy cream 1.0083.) The heart of the separator is an airtight bowl with funnellike stainless steel disks.

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

gravity flotation process for gold separation

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
