Cassiterite constitutes the chief ore of tin, as well as highly aesthetic and popular mineral specimen. Tin was a foundation of the beginning of metal smelting in the early Bronze Age and still constitutes one of the core materials of modern technology. Cassiterite is dense, resistant to abrasion, and stable in the surface Earth environment.

The element tin often occurs in nature as the oxide, SnO2. To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). This produces pure molten tin, with the carbon being removed from the reaction system as the gaseous byproduct carbon monoxide. Write the unbalanced equation for this process.

To produce pure tin metal from tin ore that is in the form of tin(IV) oxide (SnO2), the ore is heated with coal, which is primarily carbon (C). This chemical reaction is part of the process of smelting tin, and the unbalanced equation for this reaction is: SnO2(s) + C(s) → Sn(s) + CO(g) When balanced, the equation becomes:

Tin is allotropic with the normal, metallic (β) form being body-centered tetragonal above the transformation temperature, that is, ∼13.2 °C. 1 The lower temperature allotrope, α or 'gray' tin, is cubic and forms with a significant volume change that tends to result in the disintegration of the material.
