Book Free DemoGive the steps involved in the extraction of metals of low and medium reactivity from their respective sulphide ores.
\(HgS\) reacts with \(O_2\) to produce mercuric oxide and sulphur dioxide. Mercuric oxide is an unstable compound and it changes into \(Hg(l)\), which can be refined by .
\(2HgS^{4-}+3O_2→2HgO+2SO_2\)
\(HgS+X→3Hg+SO_2\)
Where X is
Roasting sulphide ore, such as \(Zn\), produces metal oxide, which is reduced with metal sulphide (\(ZnS\)) or a suitable reducing agent to produce metal, which is refined by .
\(2ZnS + 3O_2→2ZnO+2SO_2\)
\(2ZnO + ZnS→3Zn + SO_2\)
Alternative method of reduction:
\(ZnO + Y → Zn + CO\)
Where Y is .
