Advantages of extraction of copper from its sulphide ore

extraction of copper: application of metallurgycopper mining: the commonest ore used in the extraction of copper is chalcopyrite (cufes 2) also known as copper pyrites and other such sulfides. the percentage of copper in the actual ore is too low for direct extraction of copper to be viable. the concentration of ore is required and it is done by the froth flotation method. purification of copper by electrolysis metal extraction 4a. the extraction of copper from copper ores and its purification by electrolysis. copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg copper oxides or sulfides. however, in practice, modern copper smelters can actually manage the extraction without using carbon (coke) and then electrolysis is usually used to purify the impure copper from the smelter. copper mining extraction process flow chartcopper mining extraction process flow chart. this solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. this process as the advantage of avoiding the smelting and refining stages required for sulfide ores. from ore to finished productcopper - from beginning to end. copper is a major metal and an essential element used by man. it is found in ore deposits around the world. it is also the oldest metal known to man and was first discovered and used about 10,000 years ago. and as alloyed in bronze (copper-tin alloy) about 3000 bc, was the first engineering material known to man. cobalt extractionrecovery from copper-cobalt sulfide concentrates. the ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble oxides and iron into insoluble hematite. the calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte. can copper be extracted from its sulfide ore by roasting cus copper is found in the +1 oxidation state or cuprous form in its ores , so the sulfide ore of copper known as copper glance has molecular formula of cuprous sulphide(cu2s) . because copper is placed very low in the metal activity series , it is not much reactive and hence it can easily be roasted in the presence of air at high temperature to convert copper glance to copper oxide . (i) explain the steps for extraction of copper from its (i) extraction of copper metal - copper glance (cu2s): 1. concentration of the ore (removal of unwanted metals and gangue to purify the ore) is done by froth floatation method as it is a sulphide ore. 2. roasting: copper glance (cu2s) is roasted in the presence of air. roasting turns copper glance (ore of copper) into copper (i) oxide. 3. how is copper obtained from its sulphide ore give equations copper is a metal that is present low in the reactivity series. it mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. the obtained oxide is then reduced with carbon or any other suitable reducing agent to obtain the metal. nickel: smelting, producing-metalpedianickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. in many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities. copper smelting chemistry tutorial.aua copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. 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.

extraction of copper from its sulphide ore application

copper mining and extraction: oxide oresmost of the copper ores mined today are oxide or sulfide ores. extraction of sulfide ores is covered in more detail in copper mining and extraction: sulfide ores (1114), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. extraction of metals from concentrated ore: reduction of here the oxygen in the air reacts with the sulphide ores to give us oxides. the sulphur in the ore forms sulphur dioxide and separates out. here is a zinc sulphide chemical reaction. 2zns + 3o 2 2zno + 2so 2. reduction of metal oxides. this is the second step in the extraction of metals from their respective ores. copper mining and extraction: oxide orpper is refined from ores in the ground, either through underground or open-pit mines. most of the copper ores mined today are oxide or sulfide ores. extraction of sulfide ores is covered in more detail in copper mining and extraction: sulfide ores (1114), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. the extraction of copperextracting of copper from other ores. copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper(ii) sulfate solution. copper smelting chemistry tutorial.aua copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. 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 sulfide flotationbeneficiation of copper sulfide by flotation. sulphide copper ores generally occur with pyrite, pyrrhotite, arsenopyrite and molybdenite, and with gold and silver. a complete copper-iron separation may not always be essential for the maximum economic recovery and often is tied to the distribution of the gold and silver values. copper beneficiation processcopper ore divides into ore sulfide ,ore oxide and mixing ore according to its oxide rate . the main process for copper ore is flotation , for refractory mixed copper ore and refractory oxide ore , normally use hydrometallurgy process .it is a high technological enterprise that integrated research , manufacture, sales and service . copper extraction and purificationextracting copper from other ores. 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. from ore to finished productcopper - from beginning to end. it is found in ore deposits around the world. it is also the oldest metal known to man and was first discovered and used about 10,000 years ago. and as alloyed in bronze (copper-tin alloy) about 3000 bc, was the first engineering material known to man. today, copper's uses have expanded to include heating, extracting iron and copperan ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. most metals are extracted from ores found in the earth's crust. ores are often metal oxides, although sulfide and carbonate ores are also common.
