  2. Gravity separation - Wikipedia

    en.wikipedia.org/wiki/Gravity_separation

    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. Every gravitational method uses gravity as the primary force for separation.

  3. Mineral processing - Wikipedia

    en.wikipedia.org/wiki/Mineral_processing

    Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

  4. API oil–water separator - Wikipedia

    en.wikipedia.org/wiki/API_oil–water_separator

    The API separator is a gravity separation device designed using Stokes' law principles that define the rise velocity of oil droplets based on their density, size and water properties. The design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the ...

  5. Mixer-settler - Wikipedia

    en.wikipedia.org/wiki/Mixer-settler

    The height of the heavy phase weir can be adjusted in order to position the heavy/light interphase in the settling chamber based on the density of each one of the phases. The settler is a calm pool downstream of the mixer where the liquids are allowed to separate by gravity. The liquids are then removed separately from the end of the mixer.

  6. Decantation - Wikipedia

    en.wikipedia.org/wiki/Decantation

    Decanting a liquid from a solid. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.
