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.

Separation of PVC from PET/PVC Mixtures Using Flotation by ...

In this work, froth flotation was used to treat PVC (polyvinyl chloride) and PET (polyethylene terephthalate) mixtures. The parameters studied are fed mixtures component ratios, concentration of Calcium Lignosulfonate as wetting reagent and a number of cleaning flotation. The results show a yield of 100% pure PVC separated from PET.

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.

The separation process of winnowing was used in ancient cultures to separate the grain from the chaff. They would throw the mixture into the air and the wind would blow away the lighter chaff, leaving the heavier grain. High speed centrifuges can spin up to 30,000 times a minute. Many separation processes are occurring constantly in nature.
