Is smelting a refining process?

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.

Which process is direct smelting?

Processes which produce a molten product similar to blast-furnace hot metal directly from the ore are defined as 'direct smelting' processes. ... If the objective is to produce liquid steel directly from the ore, the term 'direct steelmaking' is often used.
