  2. 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.

  3. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Fractionation makes it possible to isolate more than two components in a mixture in a single run. This property sets it apart from other separation techniques. Fractionation is widely employed in many branches of science and technology. Mixtures of liquids and gasses are separated by fractional distillation by difference

  4. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  5. Fractional crystallization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Fractional_crystallization...

    In chemistry, fractional crystallization is a stage-wise separation technique that relies on the liquid–solid phase change. This technique fractionates via differences in crystallization temperature and enables the purification of multi-component mixtures, as long as none of the constituents can act as solvents to the others. Due to the high ...

  6. Magnetic separation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_separation

    Magnetic separation is also used in situations where pollution needs to be controlled, in chemical processing, as well as during the benefaction of nonferrous low-grade ores. [ 1 ] Magnetic separation is also used in the following industries: dairy, grain and milling, plastics, food, chemical, oils, textile, and more.

  7. Separatory funnel - Wikipedia

    en.wikipedia.org/wiki/Separatory_funnel

    A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities. [1]

  8. Centrifugation - Wikipedia

    en.wikipedia.org/wiki/Centrifugation

    Density gradient centrifugation is known to be one of the most efficient methods for separating suspended particles, and is used both as a separation technique and as a method for measuring the density of particles or molecules in a mixture. [17] It is used to separate particles on the basis of size, shape, and density by using a medium of ...

  9. Thin-layer chromatography - Wikipedia

    en.wikipedia.org/wiki/Thin-layer_chromatography

    Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. [1]It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. [2]
