The elements or compounds which occur naturally in the earth's crust are known as minerals.
The mineral from which a particular metal can be profitably extracted is called ore.
Gold is very less reactive whereas aluminium is a very reactive element. Therefore, aluminium reacts with other elements or compounds more than gold. Thus, aluminium occurs in combined state while gold occurs in free state
