1. Filtering or straining : To separate insoluble substances from the solution, we use the method of filtering.
2. Sifting: Sifting is done to separate solids of various sizes. The larger particles and the smaller particles can be separated by sifting.
3. Picking and sorting: The substances which are lighter in weight and those that are unwanted are removed from the mixture. The grains in the farm are particularly cleaned by the process of winnowing.
4. Combing with magnet : If there is adulteration of semolina with iron, the magnet is combed through it to remove these iron particles. The mixture that contains iron particles is specially combed with a magnet.
