Nothing; the only reason for sifting flour is to break up lumps and introduce air so that the result of baking is lighter.

No, it is not. Throw it into a sieve and you can get the flour back and keep the rice. A method of filtration if you will.
Use a sifter; the flour will fall through while the rice is caught by the screen.
Flour can be separated from the mixture by sieving as they are fine particles. Peanuts can be separated from the rice by handpicking as they are bigger in size.
due to different size of particles during milling process
An example of sieving is when you use a sieve or strainer to separate larger particles from smaller ones. For instance, sifting flour to remove lumps and break up clumps is a common example of sieving in cooking and baking.

A common method to separate cornstarch and flour mixture is through sieving. By passing the mixture through a fine sieve, the cornstarch, which is finer in texture compared to flour, can be separated as it will pass through the holes more easily, leaving the flour behind. This process helps to effectively separate the two components based on their particle sizes.
