First the ore is enriched by a process called flotation. Powdered ore is mixed water as a slurry and then further mixed with oil and a chemical called amyl xanthate. Compressed air is then blown through the mixture. The flotation process is dependent on pine oil droplets (Pine oil is just an example.) The less dense copper sulphide particles are carried to the top and are skimmed off.
The next step carried out in an oxygen flash furnace is heated using natural gas to a high temperature. Next added is limestone and sand, and fresh copper ore concentrate is blown into the furnace with oxygen. It is heated and the combustion with oxygen is endothermic.
The silicone dioxide in the sand reacts with the limestone and part of the ore (often iron oxide) to form slag. At the same time another element (often sulphur) melts and flows out of the bottom of the furnace. The slag is less dense and floats on the top.
The copper matte,(product of the previous step) is run into a converter furnace, where air containing oxygen is blown through the copper matte to oxidize the ions. At the same time some of the ions reduce the copper ions to impure blister copper metal. A final heating in an anode furnace is used to burn off the remaining oxygen.
The final step is the conversion of the impure copper to pure copper. This is done by electrolysis where the impure copper is made into the anode electrode and the pure copper is formed at the cathode electrode.

How do you extract copper by smelting?
copper is extracted by smelting by taking the copper out and melting it down.
What is the name of the process in which copper ore is reduced to copper using carbon?
smelting
How is silver mined?
Silver is mined by extracting the ore from the ground and processing it. The metal is commonly extracted from the ore by smelting or chemical leaching. It should be noted that silver is also recovered as a byproduct of the extraction of copper and some other metals.
When did metallurgy start?
If you mean smelting, then the earliest known metallurgy is copper smelting from the Vinča culture in Serbia. It might be as early as 5,5000 B.C.
How can copper be extracted from its ore?
Decomposition
How do you extract copper by smelting?
copper is extracted by smelting by taking the copper out and melting it down.
What is meant by - smelting?
Smelting is the process which ore goes through so that a metal can be extracted from it. It involves heating the rock to very high temperatures. Copper, for instance, can be extracted at temperatures of about 1200 °C.Actually, smelting is a process when a metal which is more reactive than copper needs to be extracted. For example, zinc is more reactive than copper so it has to be extracted smelting. It can be extracted by heating its ore with charcoal aka smelting.--different person
How is cobaltite extracted?
Cobalite is cobalt that has been extracted from copper and nickel. The mixture is often heated and treated using flash smelting techniques, and often, the mixture is boiled to get it to separate.
What are the pros and cons of smelting copper?
smelting causes pollution, but you are getting copper
How did Douglas Arizona get its name?
Douglas, Arizona got its name from a family by the same name. The Douglas family constructed copper smelters in Douglas, and extracted the copper ore for smelting in Bisbee, 21 miles away . The ore would be hauled to Douglas for the smelting process
What was the first metal extracted?
aluminum
What is the name of the process in which copper ore is reduced to copper using carbon?
smelting
How is silver mined?

How is copper extracted from earth?
copper is extrcted in diffrent country
How do you separate copper from it ore?
To separate copper from its ore, the process is called smelting. The copper and ore are heated and the copper turns to liquid which is then poured from the smelter.
Is copper obtained from copper ore pure?
After the initial smelting to extract copper from the ore it still has to go through electroplating purification.
When did metallurgy start?
If you mean smelting, then the earliest known metallurgy is copper smelting from the Vinča culture in Serbia. It might be as early as 5,5000 B.C.
