Three techniques for separating mixtures: filtration, chromatography, and distillation. Filtration is the process of separating suspended solid matter from a liquid, chromatography is the technique for the separation, purification, and testing of compounds, and distillation refers to the selective boiling and subsequent condensation of a component in a liquid mixture. The document also includes an image of an oil refining process infographic.

Separating
Mixtures
a separation process is commonly used to
transform a mixture of substances into two or
more distinct materials.
The separated products might differ in
chemical properties or some physical
property, such as size or crystal modification
or other separation into different
components.
Separating Mixtures
FILTRATION the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of a membrane, called a filter.
CHROMATOGRAPHY the technique for the separation, purification, and testing of compounds.
DISTILLATION refers to the selective boiling and subsequent condensation of a component in a liquid mixture. It is a separation technique that can be used to either increase the concentration of a particular component in the mixture or to obtain (almost) pure components from the mixture.
