The theoretical melting point of iron ore (pure iron) is 1538-1540℃, but the effective temperature can be significantly reduced due to chemical reduction and impurities in actual smelting. This difference reflects the wisdom of ancient metallurgical technology.

Is iron ore related to soda ash?
The relationship between iron ore and soda ash is mainly concentrated in the synergistic efficiency of metallurgical processes. Soda ash indirectly improves the smelting efficiency and steel quality through functions such as melting and desulfurization. This relationship reflects the complexity of industrial production and the necessity of synergistic utilization of resources.

The difference between iron ore and iron meteorite
Iron ore: The nickel content is very small (usually ≤3%), and the main components are iron oxides such as hematite and magnetite, without extraterrestrial elements combinations.

During magma activity, iron ore is separated and concentrated when cooling due to density differences, or chemically reacts with surrounding rocks to form iron ore deposits. This type of deposit is often accompanied by minerals such as magnetite, titanium magnetite, etc.

Is iron ore a renewable resource?
Iron ore is a mineral resource that needs to be formed after a long geological action (millions of years or even longer) and cannot be regenerated naturally within the human time scale. This is essentially different from renewable resources such as sunlight and water energy.
