why does it take less energy to make iron from scrap iron than to extract the iron from its ore?
i need this answer for science homework lmao x
the rate of reaction is very low in case of iron ore to iron. so it takes up more energy.
To start with, iron ore deposits are mainly located far from population centres. Therefore, the ore needs to be transported large distances by barge or by train before being transferred to ocean going ships. It then goes to a smelter where the iron oxides are reduced to iron which requires enormous energy expediture. Scrap iron on the other hand, may be slightly rusty but requires relatively little treatment to change it into material for re-use. Besides, scrap iron is obtained largely from established population centres that are closer to iron smelters.
