  • Chemistry for Kids: Separating Mixtures

    The separation process of winnowing was used in ancient cultures to separate the grain from the chaff. They would throw the mixture into the air and the wind would blow away the lighter chaff, leaving the heavier grain. High speed centrifuges can spin up to 30,000 times a minute. Many separation processes are occurring constantly in nature.

  • Extraction - Introduction - Separation Processes

    Introduction to Liquid-Liquid Extraction. Liquid-liquid extraction (also known as solvent extraction) involves the separation of the constituents (solutes) of a liquid solution by contact with another insoluble liquid. Solutes are separated based on their different solubilities in different liquids.Separation is achieved when the substances constituting the original solution is transferred ...

  • What is Solvent Extraction and Why is it Important?

    Solvent extraction is also widely used in the petrochemical refining industries. Extracted petroleum has lots of impurities and therefore it cannot be used for any purposes. Hence, this extraction is used to purify the product.
