The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts
Extraction of Copper Chalcopyrite (CuFeS 2) is the commonest copper oreCopper is mainly extracted from the sulphide ore (Cu 2 S) by the self-reduction process The ores ,
PREPARATION OF THE COPPER ORE This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits

Copper or An ore is a rock containing enough valuable mineral to make it worth extracting In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (02%) Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale
EXTRACTION OF COPPER On industrial scale copper is extracted from its sulphide ore known as copper pyrite (CuFeS 2) by smelting method STEPS OF EXTRACTION For more details CLICK HERE Concentration Roasting Smelting , Crushed ore is suspended in water containing pine oil A blast of air is passed through the suspension
than carbon, it can be extracted from its compounds by heating with carbon Copper is an example of this Copper mostly occurs as sulfide ores, which are heated in air to convert them to copper(II .
In extracting copper from its ores, the process of adding finely divided metallized iron ore to an ore pulp containing copper in solution; and then separating the precipitated metallic copper and other metals and sulfids present from the gangue by flotation concentration 6 In extracting copper from its ores, the process of adding a finely .
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore) Having a quick look now at how porphyry ores are treated and the metals extracted
Extraction of Copper Copper pyrites is the main ore The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate or
Extracting copper from other or Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution
After all, the nature of the ore only matters for extraction as far as the refining or metallurgy is concerned - they are almost always mined (aka "extracted" from the Earth in exactly the same two ways Rolinator 01:48, 22 July 2007 (UTC) Agreed and removed the fromation/mining sections Do we need a name change? Copper extraction from ores?

Extraction of Metals Extraction of Copper Copper is sometimes found as native metal Copper ores include copper(II) oxide and copper(II) sulfide Copper(II) oxide can be reduced by reaction with carbon Some copper ores may contain only small amounts of copper These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable
Extraction of Copper Copper is a valuable asset to us and has been used for over 5000 years It is used in plumbing, electrical wires, money (alloys), jewellery, ornaments and many other different objects
Copper is extracted from its principal ore copper pyrites (CuFeS 2) The ore is concentrated by froth flotation process The concentrated ore is roasted in a reverberatory furnace when the following reactions occur 1 The volatiles like sulphur and arsenic escape as gases S + O 2----->SO 2 4AS + 3O 2---- ,
Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit On the other hand, while copper sulfide ores are less abundant, they contain higher .

Smelting and Extraction Sulfide Ore The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations At the end of this smelting process the copper is about 99% pure Oxide Ore The copper-bearing solution is collected and pumped to the extraction plant where it is purified
Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time Copper can then be extracted from the copper(II) sulphate solution But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means
