Copper extraction refers to the methods used to obtain copper from its oresThe conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors As in all mining operations, the ore must usually be beneficiated (concentrated)Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore Open pit: 90% of ore is mined by this method Ores near the surface can be quarried after removal of the surface layers The ore is treated with dilute sulfuric acid This trickles slowly through the ore dissolving copper to formCopper Mining and Extraction Sulfide Ores
EXTRACTION OF COPPER IMPORTANT ORES OF COPPER Copper pyrite or chalcopyrite (CuFeS 2) Chalocite (Cu 2 S) or copper glance Malachite green [CuCO 3Cu(OH) 2] Azurite blue [2CuCO 3Cu(OH) 2] Bornite (3Cu 2 SFe2S 3) or peacock ore Melaconite (CuO) etc EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyritethan 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(IIExtracting iron and copper Reactions of metals AQA
Copper ore is extracted using two basic methods of mining open pit or underground mining 3 Processing of Copper Ore The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces This is accomplished by a variety of subsequent processing steps 4 Beneficiation of Copper Ore The next step in processing is called beneficiation This isExtraction 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 Bioleaching andGCSE CHEMISTRY Extraction of Copper Thermal
Copper can be extracted from its ores by reduction One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper 2 CuO + C → 2 Cu + CO2 The resulting copper, however, is purethan 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(IIExtracting iron and copper Extracting and using metals
01/01/2018· Extraction of copper from its ore is reported Leaching of copper from its ores A sample, 2000 g, of the ore was weighed and placed into a 1 L beaker and 5000 ml of 20 M HCl was added The mixture was left to equilibrate for 1 h The resulting solution was filtered and the filtrate transferred into a volumetric flask then diluted to 1 L 26 Preparation for chicken waste solution A01/11/2021· A copper ore sample from Southeast Asia was used in the leaching experiments The chemical composition of the ore is indicated in The copper extraction reached its maximum when free acidity was about 10 g/L, then slightly decreased, and remained constant with further increase of free acidity Contrary to copper, the iron leaching efficiency increased with increasing free acidity andExtraction of copper from complex carbonaceous sulfide ore
The copper ore has to be dug from the ground The ore contains some copper mineral and lot of waste rock The copper mine in picture 4 produces 6 tonnes of copper from every 1000 tonnes of ore Extraction: An ore has to be changed chemically into the metal This process is called reduction How this is done, and how much it costs, depends upon the metal's reactivity (see reactivity propertiesThe extraction of copper from ore is normally carried out in three major steps The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper The second stepcopper processing Ores | Britannica
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 Bioleaching andAlthough 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 amounts of copper Although the processing costs are higher, ultimately more copper can be extracted Since each mine site is unique in its mineral composition, concentrationCopper Mining and Processing: Processing Copper Ores
Answer: The second step in the extraction of copper from it's ore depends on the process being used designed based on the ore type For example the process for oxide copper ore will be different from that for sulphide copper ore The oxide ore may need to be leached directly while the sulphide coIn the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agentIn the extraction of copper from its sulphide ore, the
