Flotation - Separating Mixtures and Solutions

FLOTATION SEPARATION. Flotation Separation is a way of separating mixtures. It is used to separate substances by whether they float or sink. When a mixture is put into a tube and is stirred, the lighter substance should rise above the heavier substance. The substances are then separated and can be removed separately. next Page.

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.
