How does a magnet separate mixtures?

It will separate when one of the elements found in the mixture is magnetic. This process can't be done in a compound as a compound is chemically bonded!

It can only do that when one of the components of the mixture is a magnetic

material.

When you have that situation, you pass the magnet over the mixture ... shaking

the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of

the mixture moves toward the magnet, while the nonmagnetic parts of the mixture

couldn't care less about the magnet and they just stay where they are.
