Name the method used to separate the pieces of stone from grain.
Handpicking is the method used to separate the pieces of stone from grain.
[Extra information:
Handpicking is the simplest technique or method for separating unwanted substances or impurities by hand. It involves simply picking out one of the components from the mixture, which is in a small quantity compared to the others.
Use: This method is used when items differ from each other on the basis of color, shape, size, and weight.
Advantage: It is a simple and easy method. This method doesn't need any machinery for separating impurities or unwanted substances, so it is manual labor.
Disadvantage: This method takes time and is prone to errors, especially when the mixture is small in size.
For example, small pieces of stones are separated from the wheat, rice, and pulses. (on the basis of shapes and size.)
-separate chilies from the basket of a lady's finger. (on the basis of size)
- separating lentils from the rice. (on the basis of color and shape)]
