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.

US3926789A - Magnetic separation of particular mixtures ...

Particulate mixtures of non-magnetic or paramagnetic materials are separated by selectively coating the surfaces of a component or components of the mixture with a magnetic fluid. Thereafter, the particulate mixture is subjected to a magnetic separation yielding a magnetic fluid-coated fraction and a non-magnetic fraction. The process is especially useful in mineral beneficiation wherein a ...
