Copper ore is called CHALCOPYRITE.
it is about 25 or more years so suck balls
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.
When sulphide ore is heated in air it is converted into copper oxide and SO2 is left. Again, copper oxide is then reduced to copper on heating( for equation, refer 10th CBSE text, pg no. 51)
It depends upon nature of ore the most common ore of copper is Copper pyrite CuFeS2. the extraction of copper from this ore involves the following steps, 1-crushing, 2-grinding, 3-concentration of ore, 4-roastiong, 5-smelting, 6- preparation of blister copper and 7- electrorefining of blister copper.
Many Scientists believe there are only 64 years of the iron ore left! :L

The mineral malachite is an ore of copper.
A refinery separates copper from its ore.
Most copper ore occurs as copper in combination with oxygen, yes.
Because an ore contain many components which are not uniformly distributed in the mass.
