They are elements. However, pure iron, gold and copper are produced from naturally occuring ores. In that respect, they are produced.

The products of the reaction between iron and copper(II) nitrate are iron(II) nitrate and copper metal. Iron displaces copper in the compound because it is more reactive, leading to the formation of iron(II) nitrate and copper.
while electrical conductivity is shared by Gold copper AND iron.. malleability is the property shared by gold and copper but not iron
Jewelry can be made from iron, silver, copper, and gold. It is melted down and formed into lovely pieces.
The products of this single replacement reaction are iron(II) nitrate and copper. The iron displaces the copper in the reaction, resulting in the formation of iron(II) nitrate and elemental copper.
The iron will replace the copper in the copper(II) nitrate solution, forming iron(II) nitrate and copper metal as products. The balanced chemical equation for the reaction is: Fe + Cu(NO3)2 -> Fe(NO3)2 + Cu.
Gold is denser than copper and iron. This is because the density of a material is determined by its mass per unit volume, and gold has a higher atomic mass than copper and iron, making it denser. So, 1kg of gold would occupy less volume compared to 1kg of copper or iron.
