Separation process - Wikipedia

  

2019-10-16  A separation process is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures.[1] At least one of results of the separation is enriched in one or more of the source mixture's constituents. In some cases, a separation may fully divide the mixture into pure constituents. Separations

Separation of Mixtures Using Different Techniques

How Is A Homogeneous Mixture Different from A Heterogeneous mixture?What Are Types of Separation Techniques?Let’s Discuss Some of The Separation TechniquesMost materials in our surroundings are mixtures of two or more components. Mixtures are either homogeneous or heterogeneous. Homogeneous mixtures are uniform in composition, but heterogeneous mixtures are not uniform in composition.Air is a homogeneous mixture and oil in water is a heterogeneous mixture. Homogeneous and heterogeneous mixtures can be separated into their components by several physical methods. The cho of separation techniques is based on the type of mixture and difference i
