Question
What is the common ore of tin and how is tin separated from it?
Step-by-Step Solution
VerifiedThe most common tin ore is cassiterite.Tin is purified by heating the ore with coal.
An ore is a material that has a solid structure and can occurnaturally in nature. Ores help in the extraction of metals/minerals. since different ores have different high concentrations of specific elements.
The most common ore of tin (Sn) is cassiterite, having a chemical formula of \({\bf{Sn}}{{\bf{O}}_{\bf{2}}}\).
Tin ispurified by heating the ore with coal, which is a process known from ancient times. In modern history, anore is first roasted to remove arsenic, sulfur, and some volatile oxides, while the remaining materials are treated with \({\rm{HCl}}\) after the reaction removes oxides of other metals.
The complete reaction is:
\({\rm{Sn}}{{\rm{O}}_2}(s)\overset{▲}{\rightarrow} + 2C(s)Sn(s) + 2CO(g).\)
