The metal that is not extracted from its sulphide ore is

Options

  1. AAluminium
  2. BIron
  3. CLead
  4. DZinc

Correct answer

A. Aluminium

Step-by-step solution

The sulphide ore of iron is iron pyrite.

Iron can be extracted from iron pyrites

Galena is the sulphide ore of lead (PbS)

The sulphide containing ore of zinc is zinc blende (ZnS)( ZnS ).

AlAl is extracted from Al2O3⋅2H2O{Al}_{2}{O}_{3} \cdot 2{H}_{2}O i.e., Bauxite ore

Hence, Iron, lead and zinc can be extracted from their sulphide ores but not aluminium.
