    Could someone please provide a technical description of the following separation processes and list the type of industries that typically employ them.

    A. Scrubbing

    B. Solvent Extraction

    C. Sorting

    Scrubber systems are a diverse group of air pollution control devices that can be used to remove particulates and/or gases from industrial exhaust streams. It controls gaseous emissions, especially acid gases. In a scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants.

    This method is employed in number of industries like battery, iron, leather etc.

    Solvent extraction is a method to separate compounds based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent. It is an extraction of a substance from one liquid phase into another liquid phase. Liquid-liquid extraction is a basic technique in chemical laboratories, where it is performed using a separator funnel.
    Solvent extraction is used in nuclear reprocessing, ore processing, the production of fine organic compounds, the processing of perfumes and other industries. In an industrial application, this process is done continuously by pumping an organic and aqueous stream into a mixer. This mixes the organic component with the aqueous component and allows ion transfer between them. The mixing continues until equilibrium is reached. Once the ion transfer is complete (equilibrium is reached), the mixture flows into a vessel, where the organic and aqueous are allowed to separate, similar to the way oil and water would separate after mixing them. Fresh material is continuously fed into the mixer, and a two continuous streams is removed from the settler (one organic, and one aqueous). The process is commonly used to process copper and uranium.
    Sorting is applied in the processing of non-ferrous metals, glass cullet, plastics, and building rubble.. It may be done either by physical or mechanical method. For processing of non-ferrous metal, sorting is employed for the removal of the metallic waste with the help of magnet.
    The process is usually employed in glass, plastic and rubber industries.
