It's a sort of vicious circle.
Gold is expensive so it is much in demand.
So gold is extracted from rocks where it forms an ounce or less in every ton of rock - which is expensive!
Iron is not so rare and is easier to extract.
Bauxite ore is the base for aluminium and is more plentiful than gold ore. It is also cheaper to polish to the finished product. Aluminium has many more uses than gold so is readily adaptable to the consumer market. by Ruwayda :)
Iron became more widely used than bronze because it was more readily available and easier to extract from ores. Iron also had other advantages over bronze, such as being harder and more durable, making it better for tool and weapon production. Additionally, iron was cheaper and more abundant than bronze, making it accessible to a larger number of people.
Enthalpy of combustion of aluminium is much more intensive than that of iron.
gold is more expensive than iron simply because iron is more common and gold is also a purer metal
Because gold is found naturally
There have been times when iron was more valuable than gold. Most bronze age civilizations valued iron more highly than gold, as it was both rarer (iron ore is common, naturally occurring pure iron is not) and more useful (iron is significantly stronger than bronze, and much, much stronger than gold).
No, gold is around twice more expensive than iridium.
Using scrap iron to extract copper from a copper salt solution is cost-effective because iron is cheaper and more readily available than other reductants. Additionally, scrap iron helps in the reduction of copper ions to copper metal due to its high reactivity, making the extraction process efficient.
It's Cheaper
Steel was lighter, cheaper, and stronger than iron, allowing for constructions and technologies that were impossible before. Steel was important to Second Industrial Revolution because it was much lighter compared to iron. --------------- It was cheaper than iron.
