14) Smelting of iron ore involves . A) crushing and heating the ore to its melting point B) heating the ore beyond iron's melting point and combining the material with carbon C) washing the ore with acid to extract iron D) dissolving the ore in hot water to separate iron and aluminum E) oxidizing iron to ferric oxide and then adding silicon and boron

B) heating the ore beyond iron's melting point and combining the material with carbon

Explanation:

A ore is a rock that contains utilitarian materials; primarily a rock containing metals or gems which at the time of the rock's evaluation and proposal for extraction and are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values.

Smelting is a term used in metallurgy which involves the process of melting or fusion, especially to extract a metal from its ore.

The temperature at which the solid and liquid phases of a substance are in equilibrium is called the melting point. It is relatively insensitive to changes in pressure.

For smelting of iron ore it involves heating the ore beyond iron's melting point and combining the material with carbon.
