Separating Mixtures: Integrated Physics and Chemistry
Sometimes, though, it is not practical or safe to use your fingers (or a fork or tweezers) to separate the pieces of a mixture. In such cases, a process called screening could be used to separate different pieces of the mixture based on their particle size. In the screening process, a series of different screens are used to sift smaller ...

how to separate sand and gravel
Stir the mixture gently to agitate the water and help the materials separate. As you stir, the heavier gravel particles will sink to the bottom of the container, while the lighter sand particles will float to the top. Use a fine mesh screen or a slotted spoon to scoop the floating sand particles out of the water, leaving the gravel behind.
