Processes copper mining and production Copper is found in natural ore deposits around the world This page explains copper mining the production route taken from orecontaining rock to a final product that is the highestpurity commercial metal in existence and used in a wide variety of applications essential to modern living Copper has low resistivity and high immunity to electromigration The processing speed of the electronic devices increased to a great extent with the introduction of copper material Since the removal of copper during machining was not so easy as that of aluminum hence copper CMP technology The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States Today the United States and Chile are the worlds top two copper producing countries followed by Russia Canada and China

Copper processing Roasting smelting and converting

In comparison with Sumitomo a pioneer in copper mining Furukawa was anxious to introduce modern technology but realization came only in later years Even as late as 1881 Furukawa was still relying on manual crushers and leather footblowers instead of steampowered crushers and Copper A Metal Used Through The Ages Copper was one of the first metals ever extracted and used by humans and it has made vital contributions to sustaining and improving society since the dawn of civilization Copper was first used in coins and ornaments starting about 8000 BC and at about 5500 BC copper tools helped civilization emerge from the Stone Age The advancements made in mining equipment such as those achieved at General Kinematics along with mining technology progress have resulted in growth and production in the copper mining industry From primitive cumbersome mining methods to compact efficient modernday equipment copper mining has become a costeffective efficient process
