Copper is extracted from its ores by chemical processes that involve heat or electricity (roasting ores in a smelter–furnace and purification by electrolysis – all the details below) Because of its position in the reactivity series of metals copper can be extracted using carbon in a smelting furnace
3 Purpose To provide a high level overview of specific energy consumption for copper extraction processes from ore in the ground to final salable cathode product (i e mining through

The concentrated (enriched) ore can contain up to 35% copper and a number of impurities such as antimony arsenic and lead Roasting : reduces impurities in the copper ore and produces calcine (a mixture of products) * Concentrated (enriched) ore is heated to between 500 o C and 700 o C in air
Approximately 70% of the world's copper reserves are contained in the mineral chalcopyrite (Thomas 2009) Thus chalcopyrite the most common ore of copper occurs and widely distributed in metallic veins associated with pyrite (FeS 2) phyrrhotite (Fe 7 S 8) bornites (Cu 5 FeS) chalcocite (Cu 2 S) sphalerite (ZnS) galena (PbS) calcite (CaCO 3) siderite (FeCO 3) dolomite (CaCO 3 ∙MgCO 3) etc

Apr 23 2015It dates to 1750 BC and is from an unsatisfied copper ore customer named Nanni written to his supplier Ea-nasir
A typical copper ore contains between 0 5% and 2 0% copper A high grade ore produces a high yield of metal A low grade order produces a low yield of metal Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC

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) These produce many millions of tonnes of copper ore per year The main ores of copper are sulfides and
How Is Iron Extracted From the Earth? Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast furnace
