Usually by a combination of air jets and filter screens.
Substances are pure and have a specific chemical composition, while mixtures are a combination of two or more substances that can be separated physically. Substances have specific properties that do not change, while mixtures can have variable properties depending on the ratio of the components.
Aluminum can be separated into its elements because it is a pure substance composed of only one type of atom. Similarly, nitrogen can be separated into its elemental form because it is a diatomic molecule. Zinc, on the other hand, is already an element and cannot be separated into simpler substances through normal chemical processes.
'separated three substances' is past tense.
A mixture is a combination of two or more substances that do not create a new material and can usually be separated through physical means. A compound is a combination of two or more substances that chemically react to form a new material with different properties.
