which separation method would you use to separate a mixture of lead and aluminum pellets?

Heat it to 300 to 400 degrees Celsius, the lead would melt and the Aluminum would stay in solid form.

Lets get a few things straight. Aluminum does not float in water it is 2.7 times as dense as water. Neither aluminum or lead is attracted to a magnet. By an large anything that is not mostly iron will not be attracted to a magnet. The simplest way to separate these is by winnowing. That is, you use the large density difference (2.7 gm/cc vs. 11.3 gm/cc) and a flow of air or water to separate. First try setting up a good sized fan and pour the pellets down across the air stream. The aluminum pellets will be blown farther away than the lead. You can catch them separate bins. If you can't get enough separation you might need to use water flow instead of air.

A centrifuge. The lead would go to the far end of the container, and the aluminum would accumulate at the top.
