Explanation:
Seiving is for something as fine as powder to go through a strainer, and separate larger objects that can't pass through.
Use of Magnet is useful if one of the objects you are going to separate will stick to the magnet, for example: pins, iron etc.
Hand Picking can be done if the objects you are separating is big enough that you can separate them even without the use of other methods.
Winnowing uses air to blow off lighter objects to separate them from slightly heavier objects, for example, blowing off rice grains to separate them from monggo seeds.
