A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.

Is a mixture a combination of two or more substances that are not chemically combined?
A mixture is what you get when you combine two substances in such a way that no chemical reaction occurs between the components and you can separate them again. Technically, the term "mixture" is used incorrectly when a recipe calls for you to mix, for example, flour and eggs. A chemical reaction does occur between those cooking ingredients. You can't undo it. However, mixing dry ingredients, such as flour, salt and sugar, does produce an actual mixture.
