The early development of copper probably was most advanced in Egypt.As early as 5000 bce, copper weapons and implements were left in graves for the use of the dead.Definite records have been found of the working of copper mines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.Online Chat
effective for small-scale operations. Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining.Online Chat
