Smelting Wikipedia

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.

the decomposition of the ore by reducing the iron(III) oxides to iron(II). More tin chloride should be added during the dissolution process to aid in dissolving the sample and to eliminate the yellow color which is characteristic of iron(III) chloride complexes. Avoid an excess of tin(II) chloride, however. Reduction with tin(II) chloride.
