The ore is called "Bauxite". The chemical formula for Aluminium Oxide is Al2O3 Note however, this is not the chemical formula for Bauxite.
The metal obtained is Copper. Malachite has the formula Cu2CO3(OH)2. The mineral has a stunning green/turquoise colour.
Copper ore is called CHALCOPYRITE.
Chalcopyrite which is a copper iron sulphide mineral with formula CuFeS2.
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.

copper ore is usually in the form of malachite, needs to be refined through chemical method.

The metal obtained is Copper. Malachite has the formula Cu2CO3(OH)2. The mineral has a stunning green/turquoise colour.
Copper ore is called CHALCOPYRITE.
Chalcopyrite which is a copper iron sulphide mineral with formula CuFeS2.
Copper ore, usually in the form of malachite, needs to be refined through a chemical reaction, rather than a mechanical separation as with washing. It needs to be ground and heated to separate out the copper metal from the compound.
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)
The mineral malachite is an ore of copper.
A refinery separates copper from its ore.
