An element is a pure substance as it cannot be broken down or transformed into a new substance even by using some physical or chemical means. Components of a homogeneous mixture cannot be separated by using physical methods. For example, a mixture with components that have different boiling points may be best separated by distillation, while a mixture with components that adhere to solid surfaces differently may require chromatography. We indicated that the components of a mixture could be separated by physical means, but the components of a pure substance could not. In such cases, centrifugal decantation or sedimentation decantation methods could be used. Unlike traditional magnetic separation, this method makes use of electromagnets instead of permanent magnets to isolate magnetic materials from non-magnetic ones.
