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 is a separation technique used to separate the components of a mixture containing an undissolved solid in a liquid. Filtration may be done cold or hot, using gravity or applying vacuum, using a Buchner or Hirsch funnel or a simple glass funnel . The exact method used depends on the purpose of the filtration, whether it is for the isolation of a solid from a mixture or removal of

To separate colors in a dye. To separate pigments from natural colors. To separate drugs from blood. Centrifugation Sometimes the solid particles in a liquid are very small and can pass through a filter paper. For such particles, the filtration technique cannot be used for separation. Such mixtures are separated by centrifugation.
