: Tin Oxide + Carbon → Carbon Dioxide + Tin
: Lead Oxide + Carbon → Carbon Dioxide + Lead
==Key Stage 4==
===Meaning===
[[Smelting]] is a process for [[Extraction of Metals|extracting metals]] by heating and [[melting]] a [[mineral]] with [[carbon]] to cause a [[Displacement Reaction|displacement reaction]].
===About Smelting===
: Any [[metal]] below [[Carbon]] on the [[Reactivity Series]] can be [[Extraction of Metals|extracted]] from its by [[smelting]] with [[Carbon]].
: When the [[ore]] is [[melting|melted]] it [[Carbon]] is added and a [[Displacement Reaction|displacement reaction]] happens where the [[Carbon]] replaces the [[metal]] in the [[mineral]].
===Example Reactions===
Iron Oxide + Carbon → Carbon Dioxide + Iron
: <chem>2Fe2O3 + 3C -> 3CO2 + 4Fe</chem>
Zinc Oxide + Carbon → Carbon Dioxide + Zinc
: <chem>2ZnO + C -> CO2 + 2Zn</chem>
Tin Oxide + Carbon → Carbon Dioxide + Tin
: <chem>SnO2 + C -> CO2 + Sn</chem>
Lead Oxide + Carbon → Carbon Dioxide + Lead
: <Chem>2PbO + C -> CO2 + 2Pb</chem>
Zinc Carbonate + Carbon → Carbon Dioxide + Zinc
: <chem>2ZnCO3 + C -> 3CO2 + 2Zn</chem>
Copper Carbonate Hydroxide + Carbon → Carbon Dioxide + Water + Copper
: <chem>Cu2(CO3)(OH)2 + C -> 2CO2 + H2O + 2Cu</chem>
