Key Question: How can you separate mechanical mixtures?

Some mechanical mixtures can be separated by hand. Others are made of parts too small to separate by hand. There are different ways that you can separate mechanical mixtures: • sorting • floating • settling • using a magnet • using sieves and filters • dissolving 1. Sorting The simplest way to separate mechanical mixtures is by sorting.
