123 Primary Copper SmeltingCopper Mining and Extraction Sulfide Ores
16 millon tons of ore produced in Copper is produced in the U S primarily by pyrometallurgical smelting methods Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrat Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining An ore is a rock or mineral that has enough metal in it to make it worth extracting Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile Escondida mine and Indonesia Grasberg mine

Iron Ore Mining Techniques Metal Extraction Types of The 10 Biggest Mining Stocks The Motley Fool
Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the Iron ore for example is a key component in steel while the automotive and aerospace sectors use lots of aluminum and copper is crucial for electricity production Because of that the mining
