copper processing | Definition, History, & Facts | Britannica

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.60 Centuries of Copper: Its Effect on Copper Mining,The cost of copper, in those days, was very great. In 1714 cake copper, unrefined, fetched £100 per ton, and plates as they came from the battery works cost £140 to £150 per ton. In 1694 Swedish copper, which was then regarded as high quality, cost £168 per ton. These figures, currency for currency, far exceed modern prices.Chapter 6 Copper Production Technology,Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores.
