What is handpicking? Give examples.

Handpicking is a simple method of separation in which unwanted substances are removed manually by hand. It is used when the particles are large, visible, and present in small quantities.

This method works best when there is a clear difference in size, shape, or appearance between the components of a mixture.

For example, removing stones, husk, or spoiled grains from rice or pulses is a common use of handpicking. It is also used to separate insects or dirt from vegetables.

In simple terms, handpicking is a basic and effective method used in daily life when impurities can be easily identified and picked out by hand.
