• chemical and physical separation methods for iron

    Lab #2 PHYSICAL SEPARATION TECHNIQUES Introduction. The separation of the components of a mixture is a problem frequently encountered in chemistry. The basis of the separation is the fact that each component has a different set of physical and chemical properties. The components are pure substances which are either elements or compounds.
