How do you separate powdered iron and powdered aluminum mixture?
One way to separate powdered iron and powdered aluminum mixture is by using a magnet to attract the iron particles, as iron is magnetic while aluminum is not. You can pass a magnet over the mixture to pull out the iron particles, leaving the aluminum behind. Another method is to use the difference in their melting points, since aluminum has a lower melting point than iron, you can heat the mixture to a temperature where only aluminum melts, allowing you to separate the two components.
