Separation Techniques - Substances and Mixtures

Substances and Mixtures. The simplest way of separating mechanical mixtures is by sorting. Sorting is used when the two (or more) types of matter are in fairly large pieces. Sorting simply involves looking at the various parts and physically moving one or more of the parts into a different container. The parts of many mechanical mixtures ...

Methods for Separating Mixtures Chemistry for Non-Majors

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
