Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
Jun 23, 2019· A smelting pot is the container used to melt ore and other ingredients into a liquid that can be poured into molds to be given a working shape. Commonly created from very heavy cast iron and lined with brick, ceramic tile or some other type of heat barrier, the pot is able to withstand extreme heat for many smelting cycles without burning through or weakening.
Difference between Melting and Smelting. Tweet. Key Difference: Melting is the process of changing a substance from solid to liquid form. This is generally done by heating the substance. However, smelting is a process to convert a substance or ore to its purest form by chemical reactions.
Smelting maximizes the separation of ore from gangue minerals. The concentrates undergo smelting and converting in a furnace at a high temperature to produce a silicate melt (slag) and an immiscible melt (matte) due to density differences. The flux (limestone) is added to the furnace to reduce the melting temperature in the matte.

Transforming alumina -- aluminum oxide -- into aluminum represented a major milestone in the industrial revolution. Until modern smelting techniques evolved, only small quantities of aluminum could be obtained. Most early processes relied on displacing aluminum with more reactive metals, but the metal remained expensive and relatively elusive.
