In the first era, man knew something about metals. Indeed, most of his tools were made of stone, bone, or animal horns. Perhaps gold, with its luster and shine, was the first metal that caught his attention. There are remains of gold jewelry discovered along with tools made of polished stone dating back to To the stone ages. This is clear evidence that gold is the first metal known to man.
The second metal is copper, and there is a saying that the Egyptians knew it before they knew gold, and they extracted it from its carbonates, which are the most important ores and were sourced from the Sinai Desert. Copper traces were discovered in Egypt dating back to 3500 years BC.
It is also said that the first people to engage in mining were the people of Iraq, but it is proven that this industry was also known to the people of Egypt and the inhabitants of the island of Crete since 3400 years BC, and that gold, silver, copper, bronze, lead and iron are among the metals that were known to them, and it is also proven that the ancient Egyptians They used iron, silver, and lead after they used copper. As for gold, the country knew it before the era of dynasty, that is, before the era of King Menes (3400 years BC).
