Give the Formula of Copper Pyrite

Give the formula of copper pyrite.

Pyrite, often known as iron pyrite, is the most common sulphide mineral. The majority of copper ores are found in nature as sulphides. Copper pyrite is essential copper ore. Chalcopyrite is the most popular name for it.

Iron or pyrite Pyrite is an iron sulphide mineral with the chemical formula FeS₂.CuCO₃ can be ruled out of the choices listed above.Cu(OH)₂ and Cu₂O, since they are not sulphides.Cu₂S is not a pyrite mineral but rather copper sulphide. Copper pyrite is copper iron sulphide with the chemical formula CuFeS₂.

Copper metal may be obtained from copper pyrite by extraction. Copper iron sulfide (CuFeS₂) is first concentrated using froth flotation. Then it is roasted in a reverberatory furnace, which means that it is heated in an environment with an abundance of oxygen. 

Copper pyrite, when heated, produces a compound that is a combination of cuprous sulphide and iron sulphide, sometimes known as ferrous sulphide (FeS) (Cu₂S).

2CuFeS₂ + O₂ → Cu₂S + 2FeS + SO₂

The formation of ferrous oxide begins with ferrous sulphide (FeS) oxidation.

2FeS + 3O₂ →2FeO + 2SO₂

Because copper is less reactive than iron, cuprous sulphide does not oxidize into copper oxide. This is because copper is less reactive than iron (Cu₂O). If any Cu₂O is produced, FeS will react with it and convert it into Cu₂S, which may also be written as Cu₂S.

2Cu₂S + 3O₂ → 2Cu₂O + 2SO₂

Cu₂O + FeS → Cu₂S + FeO

After that, FeS and Cu₂S are combined with silica (SiO₂), and the resulting mixture is then heated in a furnace. When FeO is combined with SiO₂, the result is ferrous silicate (FeSiO₃). Slag is another name for FeSiO₃, which, due to its lower density, floats on top of the molten layer of copper mate, which is composed of Cu₂S and unreacted FeS. The last step is extracting copper from copper matte.
