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 can copper be extracted from its ore?
Copper can be extracted from its ore through a process called smelting. The ore is first crushed and then heated in a furnace to separate the copper from the other elements. The molten copper is then collected as a metal.
How do you extract copper by smelting?
Copper ore is first crushed and ground into a fine powder. It is then heated in a furnace along with a reducing agent such as carbon or coke, which removes oxygen from the ore and leaves behind the copper. The molten copper is then cast into molds to form solid copper bars or ingots.
How is coppper exstracted from its ore?
Copper is extracted from its ore through a process called smelting, where the ore is heated to high temperatures in a furnace with carbon, which reduces the copper oxide to copper metal. The molten copper can then be cast into shapes or further processed to purify it.
How is copper obtained from its pure form?
Copper is mainly obtained through mining of copper ores. The ore is then crushed and ground to release the copper minerals. The copper is then extracted using a process called smelting, which involves heating the ore with a reducing agent to remove the impurities and obtain pure copper metal.
How is copper extracted from copper-rich ores?
Copper is typically extracted from copper-rich ores through a process called smelting. This involves heating the ore to high temperatures in a furnace with a reducing agent such as carbon, which separates the copper from the ore. The copper is then further refined through processes like electrolysis to produce pure copper metal.
How can copper be extracted from its ore?

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
What was the first metal extracted?
The first metal extracted by humans was likely copper, as it is relatively easy to extract from its ores using simple techniques like heating or smelting. Copper was used for making tools, weapons, and ornaments by early human civilizations.
How is copper extracted from phytomining?
In phytomining, plants absorb copper from the soil through their roots. Once the plants accumulate enough copper, they are harvested and burnt. The copper is extracted from the ash through a process known as smelting.
Can copper be extracted from its compounds using carbon?
Yes, copper can be extracted from its compounds using carbon through a process called smelting. The carbon reduces the copper oxide to metal, forming carbon dioxide as a byproduct. This process is commonly used in the extraction of copper from ores such as copper oxide.
How do you extract copper by smelting?
Copper ore is first crushed and ground into a fine powder. It is then heated in a furnace along with a reducing agent such as carbon or coke, which removes oxygen from the ore and leaves behind the copper. The molten copper is then cast into molds to form solid copper bars or ingots.
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.
How can copper be extracted using scrap iron nothing it doesnt work that way?
Copper cannot be extracted using scrap iron because iron is less reactive than copper in the reactivity series. To extract copper from its ore, a process called electrolysis or smelting is usually used. During smelting, the copper ore is heated with carbon to remove oxygen and extract the copper metal.
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
