Answer:
The first recorded metals used were those found, in an unreacted state referred to as 'Native Metals'. These metals could be mined and used without the need of more complicated extraction or separation from other metals or nonmetallic atoms. Most metals naturally occur as minerals or compounds, where the metal atom has reacted with other metals or nonmetallic atoms, one of the key steps of the development of Metallurgy as a science, revolves around the extraction of metals from their naturally states.
The discovery of the first metal by man becomes his first step towards modernization. Man learn how to manipulate the different kinds of metals which he can put in good use as well as a tool for destruction.
Before the discovery of metal, man lived in a time period that is the "Stone Age" about 6,000 BC.It is called such because man made majority of his tools and weapons out of stone.In this period he had not yet discovered or learns to use metals.
The first discovery of metal probably happens during the period of 4000 BC.And the first metal that was used by man was copper and gold.This is because, these metals occur in nature in a free state to which they are not mixed with other impurities.Man probably found nuggets of copper or gold in his surroundings wherein he was able to hammer them into various shapes and forms even without heating or melting them.
There is no reliable scientific evidence for us to know the exact date when man first discovered how to use these metals ....
