Separation of Mixtures: Methods and Examples

Examples: brewing coffee, filtering water, vacuuming dust with a vacuum. Filtration. Flotation (floating) It is used, for example, to separate a mixture of sand and wood dust (sawdust). To promote this separation, just add water to this mixture; thus, the water will occupy the intermediate phase, the sawdust will float and the sand will settle.
