Jun 22, 2019· Smelting is the process of extracting the metals from ores in the purest form. It involves heat and chemicals to melt the ore and convert it into pure metals. There are two requirements of the smelting process, heat treatment, and reducing agent. Smelting obtains a metal at temperatures beyond the melting point from its ore.

Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.
