Three examples of separation of mixtures at home are:

2. Removal of grains from flour: Sieves are used to separate the grains from flour.

3. Filtration of tea or coffee: Tea leaves are used to make a black tea. The tea leaves are separated from the liquid using a strainer. The same applies to the making of coffee from coffee beans.
